The least significant byte is always transmitted first. If the TX FIFO is full and the SPIActive bit of the status register is 1, the ready signal hready/pready will be deasserted to insert wait states to the transfer. For reads, data is read and dequeued from the RX FIFO. The least significant byte is the first received byte. If the RX FIFO is empty and the SPIActive bit of the status register is 1, the ready signal hready/pready will be deasserted to insert wait states to the transfer. The FIFOs decouple the speed of the SPI transfers and the software鈥檚 generation/consumption of data. When the TX FIFO is empty, SPI transfers will hold until more data is written to the TX FIFO; when the RX FIFO is full, SPI transfers will hold until there is more room in the RX FIFO. If more data is written to the TX FIFO than the write transfer count (WrTranCnt), the remaining data will stay in the TX FIFO for the next transfer or until the TX FIFO is reset. 0 32 read-write Ctrl Control Register 0x30 32 0x00000000 0x0FFFFF1F CS_EN No description available 24 4 read-write TXTHRES Transmit (TX) FIFO Threshold The TXFIFOInt interrupt or DMA request would be issued to replenish the TX FIFO when the TX data count is less than or equal to the TX FIFO threshold. 16 8 read-write RXTHRES Receive (RX) FIFO Threshold The RXFIFOInt interrupt or DMA request would be issued for consuming the RX FIFO when the RX data count is more than or equal to the RX FIFO threshold. 8 8 read-write TXDMAEN TX DMA enable 4 1 read-write RXDMAEN RX DMA enable 3 1 read-write TXFIFORST Transmit FIFO reset Write 1 to reset.

A write access has no impact. 0 16 read-only TOCC timeout counter configuration 0x28 32 0xFFFF0000 0xFFFF0007 TOP Timeout Period Start value of the Timeout Counter (down-counter). Configures the Timeout Period. 16 16 read-write TOS Timeout Select When operating in Continuous mode, a write to TOCV presets the counter to the value configured by TOCC.TOP and continues down-counting. When the Timeout Counter is controlled by one of the FIFOs, an empty FIFO presets the counter to the value configured by TOCC.TOP. Down-counting is started when the first FIFO element is stored. 00= Continuous operation 01= Timeout controlled by Tx Event FIFO 10= Timeout controlled by Rx FIFO 0 11= Timeout controlled by Rx FIFO 1 1 2 read-write RP Enable Timeout Counter 0= Timeout Counter disabled 1= Timeout Counter enabled 0 1 read-write TOCV timeout counter value 0x2c 32 0x0000FFFF 0x0000FFFF TOC Timeout Counter The Timeout Counter is decremented in multiples of CAN bit times [1…16] depending on the configuration of TSCC.TCP. When decremented to zero, interrupt flag IR.TOO is set and the Timeout Counter is stopped. Start and reset/restart conditions are configured via TOCC.TOS. Note: Byte access: when TOCC.TOS = “00，writing one of the register bytes 3/2/1/0 will preset the Timeout Counter. 0 16 read-only ECR error counter register 0x40 32 0x00000000 0x00FFFFFF CEL CAN Error Logging The counter is incremented each time when a CAN protocol error causes the 8-bit Transmit Error Counter TEC or the 7-bit Receive Error Counter REC to be incremented. The counter is also incremented when the Bus_Off limit is reached. It is not incremented when only RP is set without changing REC. The increment of CEL follows after the increment of REC or TEC. The counter is reset by read access to CEL. The counter stops at 0xFF; the next increment of TEC or REC sets interrupt flag IR.ELO. Note: Byte access: Reading byte 2 will reset CEL to zero, reading bytes 3/1/0 has no impact. 16 8 read-only RP Receive Error Passive 0= The Receive Error Counter is below the error passive level of 128 1= The Receive Error Counter has reached the error passive level of 128 15 1 read-only REC Receive Error Counter Actual state of the Receive Error Counter, values between 0 and 127 8 7 read-only TEC Transmit Error Counter Actual state of the Transmit Error Counter, values between 0 and 255 Note: When CCCR.ASM is set, the CAN protocol controller does not increment TEC and REC when a CAN protocol error is detected, but CEL is still incremented. 0 8 read-only PSR protocol status register 0x44 32 0x00000707 0x007F7FFF TDCV Transmitter Delay Compensation Value Position of the secondary sample point, defined by the sum of the measured delay from m_can_tx to m_can_rx and TDCR.TDCO. The SSP position is, in the data phase, the number of mtq between the start of the transmitted bit and the secondary sample point. Valid values are 0 to 127 mtq. 16 7 read-only PXE Protocol Exception Event 0= No protocol exception event occurred since last read access 1= Protocol exception event occurred Note: Byte access: Reading byte 0 will reset PXE, reading bytes 3/2/1 has no impact. 14 1 read-only RFDF Received a CAN FD Message This bit is set independent of acceptance filtering. 0= Since this bit was reset by the CPU, no CAN FD message has been received 1= Message in CAN FD format with FDF flag set has been received Note: Byte access: Reading byte 0 will reset RFDF, reading bytes 3/2/1 has no impact. 13 1 read-only RBRS BRS flag of last received CAN FD Message This bit is set together with RFDF, independent of acceptance filtering. 0= Last received CAN FD message did not have its BRS flag set 1= Last received CAN FD message had its BRS flag set Note: Byte access: Reading byte 0 will reset RBRS, reading bytes 3/2/1 has no impact. 12 1 read-only RESI ESI flag of last received CAN FD Message This bit is set together with RFDF, independent of acceptance filtering. 0= Last received CAN FD message did not have its ESI flag set 1= Last received CAN FD message had its ESI flag set Note: Byte access: Reading byte 0 will reset RESI, reading bytes 3/2/1 has no impact. 11 1 read-only DLEC Data Phase Last Error Code Type of last error that occurred in the data phase of a CAN FD format frame with its BRS flag set.Coding is the same as for LEC. This field will be cleared to zero when a CAN FD format frame with its BRS flag set has been transferred (reception or transmission) without error. Note: Byte access: Reading byte 0 will set DLEC to “111”, reading bytes 3/2/1 has no impact. 8 3 read-only BO Bus_Off Status 0= The M_CAN is not Bus_Off 1= The M_CAN is in Bus_Off state 7 1 read-only EW Warning Status 0= Both error counters are below the Error_Warning limit of 96 1= At least one of error counter has reached the Error_Warning limit of 96 6 1 read-only EP Error Passive 0= The M_CAN is in the Error_Active state. It normally takes part in bus communication and sends an active error flag when an error has been detected 1= The M_CAN is in the Error_Passive state 5 1 read-only ACT Activity Monitors the module’s CAN communication state. 00= Synchronizing - node is synchronizing on CAN communication 01= Idle - node is neither receiver nor transmitter 10= Receiver - node is operating as receiver 11= Transmitter - node is operating as transmitter Note: ACT is set to “00” by a Protocol Exception Event. 3 2 read-only LEC Last Error Code The LEC indicates the type of the last error to occur on the CAN bus. This field will be cleared to ‘0’when a message has been transferred (reception or transmission) without error. 0= No Error: No error occurred since LEC has been reset by successful reception or transmission. 1= Stuff Error: More than 5 equal bits in a sequence have occurred in a part of a received message where this is not allowed. 2= Form Error: A fixed format part of a received frame has the wrong format. 3= AckError: The message transmitted by the M_CAN was not acknowledged by another node. 4= Bit1Error: During the transmission of a message (with the exception of the arbitration field), the device wanted to send a recessive level (bit of logical value ‘1’), but the monitored bus value was dominant. 5= Bit0Error: During the transmission of a message (or acknowledge bit, or active error flag, or overload flag), the device wanted to send a dominant level (data or identifier bit logical value‘0’), but the monitored bus value was recessive. During Bus_Off recovery this status is set each time a sequence of 11 recessive bits has been monitored. This enables the CPU to monitor the proceeding of the Bus_Off recovery sequence (indicating the bus is not stuck at dominant or continuously disturbed). 6= CRCError: The CRC check sum of a received message was incorrect. The CRC of an incoming message does not match with the CRC calculated from the received data. 7= NoChange: Any read access to the Protocol Status Register re-initializes the LEC to ‘7’. When the LEC shows the value ‘7’, no CAN bus event was detected since the last CPU read access to the Protocol Status Register. Note: When a frame in CAN FD format has reached the data phase with BRS flag set, the next CAN event (error or valid frame) will be shown in DLEC instead of LEC. An error in a fixed stuff bit of a CAN FD CRC sequence will be shown as a Form Error, not Stuff Error. Note: The Bus_Off recovery sequence (see ISO 11898-1:2015) cannot be shortened by setting or resetting CCCR.INIT. If the device goes Bus_Off, it will set CCCR.INIT of its own accord,stopping all bus activities. Once CCCR.INIT has been cleared by the CPU, the device will then wait for 129 occurrences of Bus Idle (129 * 11 consecutive recessive bits) before resuming normal operation. At the end of the Bus_Off recovery sequence, the Error Management Counters will be reset. During the waiting time after the resetting of CCCR.INIT, each time a sequence of 11 recessive bits has been monitored, a Bit0Error code is written to PSR.LEC, enabling the CPU to readily check up whether the CAN bus is stuck at dominant or continuously disturbed and to monitor the Bus_Off recovery sequence. ECR.REC is used to count these sequences. Note: Byte access: Reading byte 0 will set LEC to “111”, reading bytes 3/2/1 has no impact. 0 3 read-only TDCR transmitter delay compensation 0x48 32 0x00000000 0x00007F7F TDCO Transmitter Delay Compensation SSP Offset Offset value defining the distance between the measured delay from m_can_tx to m_can_rx and the secondary sample point. Valid values are 0 to 127 mtq. 8 7 read-write TDCF Transmitter Delay Compensation Filter Window Length Defines the minimum value for the SSP position, dominant edges on m_can_rx that would result in an earlier SSP position are ignored for transmitter delay measurement. The feature is enabled when TDCF is configured to a value greater than TDCO. Valid values are 0 to 127 mtq. 0 7 read-write IR interrupt register 0x50 32 0x00000000 0x3FFFFFFF ARA Access to Reserved Address 0= No access to reserved address occurred 1= Access to reserved address occurred 29 1 read-write PED Protocol Error in Data Phase (Data Bit Time is used) 0= No protocol error in data phase 1= Protocol error in data phase detected (PSR.DLEC ≠ 0,7) 28 1 read-write PEA Protocol Error in Arbitration Phase (Nominal Bit Time is used) 0= No protocol error in arbitration phase 1= Protocol error in arbitration phase detected (PSR.LEC ≠ 0,7) 27 1 read-write WDI Watchdog Interrupt 0= No Message RAM Watchdog event occurred 1= Message RAM Watchdog event due to missing READY 26 1 read-write BO Bus_Off Status 0= Bus_Off status unchanged 1= Bus_Off status changed 25 1 read-write EW Warning Status 0= Error_Warning status unchanged 1= Error_Warning status changed 24 1 read-write EP Error Passive 0= Error_Passive status unchanged 1= Error_Passive status changed 23 1 read-write ELO Error Logging Overflow 0= CAN Error Logging Counter did not overflow 1= Overflow of CAN Error Logging Counter occurred 22 1 read-write BEU Bit Error Uncorrected Message RAM bit error detected, uncorrected.

In this case acceptance filtering or message storage is aborted and the Rx Handler starts processing of the following message. .was not able to write a message to the Message RAM. In this case message storage is aborted. In both cases the FIFO put index is not updated resp. the New Data flag for a dedicated Rx Buffer is not set, a partly stored message is overwritten when the next message is stored to this location. The flag is also set when the Tx Handler was not able to read a message from the Message RAM in time. In this case message transmission is aborted. In case of a Tx Handler access failure the M_CAN is switched into Restricted Operation Mode (see Section 3.1.5). To leave Restricted Operation Mode, the Host CPU has to reset CCCR.ASM. 0= No Message RAM access failure occurred 1= Message RAM access failure occurred 17 1 read-write TSW Timestamp Wraparound 0= No

Example: For a configuration of 12 dedicated Tx Buffers and a Tx FIFO of 20 Buffers a Put Index of 15 points to the fourth buffer of the Tx FIFO. 0 6 read-only TXESC tx buffer element size configuration 0xc8 32 0x00000000 0x00000007 TBDS Tx Buffer Data Field Size 000= 8 byte data field 001= 12 byte data field 010= 16 byte data field 011= 20 byte data field 100= 24 byte data field 101= 32 byte data field 110= 48 byte data field 111= 64 byte data field Note: In case the data length code DLC of a Tx Buffer element is configured to a value higher than the Tx Buffer data field size TXESC.TBDS, the bytes not defined by the Tx Buffer are transmitted as “0xCC” (padding bytes). 0 3 read-write TXBRP tx buffer request pending 0xcc 32 0x00000000 0xFFFFFFFF TRP Transmission Request Pending Each Tx Buffer has its own Transmission Request Pending bit. The bits are set via register TXBAR.The bits are reset after a requested transmission has completed or has been cancelled via register TXBCR. TXBRP bits are set only for those Tx Buffers configured via TXBC. After a TXBRP bit has been set, a Tx scan (see Section 3.5, Tx Handling) is started to check for the pending Tx request with the highest priority (Tx Buffer with lowest Message ID). A cancellation request resets the corresponding transmission request pending bit of register TXBRP. In case a transmission has already been started when a cancellation is requested, this is done at the end of the transmission, regardless whether the transmission was successful or not. The cancellation request bits are reset directly after the corresponding TXBRP bit has been reset. After a cancellation has been requested, a finished cancellation is signalled via TXBCF ? after successful transmission together with the corresponding TXBTO bit ? when the transmission has not yet been started at the point of cancellation ? when the transmission has been aborted due to lost arbitration ? when an error occurred during frame transmission In DAR mode all transmissions are automatically cancelled if they are not successful. The corresponding TXBCF bit is set for all unsuccessful transmissions. 0= No transmission request pending 1= Transmission request pending Note: TXBRP bits which are set while a Tx scan is in progress are not considered during this particular Tx scan. In case a cancellation is requested for such a Tx Buffer, this Add Request is cancelled immediately, the corresponding TXBRP bit is reset. 0 32 read-only TXBAR tx buffer add request 0xd0 32 0x00000000 0xFFFFFFFF AR Add Request Each Tx Buffer has its own Add Request bit. Writing a ‘1’ will set the corresponding Add Request bit; writing a ‘0’ has no impact. This enables the Host to set transmission requests for multiple Tx Buffers with one write to TXBAR. TXBAR bits are set only for those Tx Buffers configured via TXBC. When no Tx scan is running, the bits are reset immediately, else the bits remain set until the Tx scan process has completed. 0= No transmission request added 1= Transmission requested added Note: If an add request is applied for a Tx Buffer with pending transmission request (corresponding TXBRP bit already set), this add request is ignored. 0 32 read-write TXBCR tx buffer cancellation request 0xd4 32 0x00000000 0xFFFFFFFF CR Cancellation Request Each Tx Buffer has its own Cancellation Request bit. Writing a ‘1’ will set the corresponding Cancellation Request bit; writing a ‘0’ has no impact. This enables the Host to set cancellation requests for multiple Tx Buffers with one write to TXBCR. TXBCR bits are set only for those Tx Buffers configured via TXBC. The bits remain set until the corresponding bit of TXBRP is reset. 0= No cancellation pending 1= Cancellation pending 0 32 read-write TXBTO tx buffer transmission occurred 0xd8 32 0x00000000 0xFFFFFFFF TO Transmission Occurred Each Tx Buffer has its own Transmission Occurred bit.

In case the corresponding TXBRP bit was not set at the point of cancellation, CF is set immediately.

Abort is generated when the LCDC is going to switch bank to a new bank, and the new bank data is not ready yet. Abort is only useful when communicating with the offline calculator (such as PDMA as the active pixel generator mode). PDMA as the active generator mode, means it is the first pixel generator with data sources from offline memory, and not from on-the-fly streaming data (such as camera captured data). While with on-the-fly streaming data, error condition is indicated by display buffer underflow. 22 1 read-write HANDSHAKE_BUFSIZE 1: handshake buffer is 16 rows hight per ping or pang buf. 0: handshake buffer is 8 rows hight per ping or pang buf. 21 1 read-write ENABLE_HANDSHAKE Enable handshake with input pixel controller.

0x00000000 0x7FFFFFFF SARC Source Address Insertion or Replacement Control This field controls the source address insertion or replacement for all transmitted frames. Bit 30 specifies which MAC Address register (0 or 1) is used for source address insertion or replacement based on the values of Bits [29:28]: - 2'b0x: The input signals mti_sa_ctrl_i and ati_sa_ctrl_i control the SA field generation. - 2'b10: - If Bit 30 is set to 0, the MAC inserts the content of the MAC Address 0 registers (registers 16 and 17) in the SA field of all transmitted frames. - If Bit 30 is set to 1 and the Enable MAC Address Register 1 option is selected during core configuration, the MAC inserts the content of the MAC Address 1 registers (registers 18 and 19) in the SA field of all transmitted frames. - 2'b11: - If Bit 30 is set to 0, the MAC replaces the content of the MAC Address 0 registers (registers 16 and 17) in the SA field of all transmitted frames. - If Bit 30 is set to 1 and the Enable MAC Address Register 1 option is selected during core configuration, the MAC replaces the content of the MAC Address 1 registers (registers 18 and 19) in the SA field of all transmitted frames. Note: - Changes to this field take effect only on the start of a frame. If you write this register field when a frame is being transmitted, only the subsequent frame can use the updated value, that is, the current frame does not use the updated value. - These bits are reserved and RO when the Enable SA, VLAN, and CRC Insertion on TX feature is not selected during core configuration. 28 3 read-write TWOKPE IEEE 802.3as Support for 2K Packets When set, the MAC considers all frames, with up to 2,000 bytes length, as normal packets. When Bit 20 (JE) is not set, the MAC considers all received frames of size more than 2K bytes as Giant frames. When this bit is reset and Bit 20 (JE) is not set, the MAC considers all received frames of size more than 1,518 bytes (1,522 bytes for tagged) as Giant frames. When Bit 20 is set, setting this bit has no effect on Giant Frame status. 27 1 read-write SFTERR SMII Force Transmit Error When set, this bit indicates to the PHY to force a transmit error in the SMII frame being transmitted. This bit is reserved if the SMII PHY port is not selected during core configuration. 26 1 read-write CST CRC Stripping for Type Frames When this bit is set, the last 4 bytes (FCS) of all frames of Ether type (Length/Type field greater than or equal to 1,536) are stripped and dropped before forwarding the frame to the application. This function is not valid when the IP Checksum Engine (Type 1) is enabled in the MAC receiver. This function is valid when Type 2 Checksum Offload Engine is enabled. 25 1 read-write TC Transmit Configuration in RGMII, SGMII, or SMII When set, this bit enables the transmission of duplex mode, link speed, and link up or down information to the PHY in the RGMII, SMII, or SGMII port. When this bit is reset, no such information is driven to the PHY. This bit is reserved (and RO) if the RGMII, SMII, or SGMII PHY port is not selected during core configuration. 24 1 read-write WD Watchdog Disable When this bit is set, the MAC disables the watchdog timer on the receiver. The MAC can receive frames of up to 16,383 bytes. 23 1 read-write JD Jabber Disable When this bit is set, the MAC disables the jabber timer on the transmitter. The MAC can transfer frames of up to 16,383 bytes. When this bit is reset, the MAC cuts off the transmitter if the application sends out more than 2,048 bytes of data (10,240 if JE is set high) during transmission. 22 1 read-write BE Frame Burst Enable When this bit is set, the MAC allows frame bursting during transmission in the GMII half-duplex mode. This bit is reserved (and RO) in the 10/100 Mbps only or full-duplex-only configurations. 21 1 read-write JE Jumbo Frame Enable When this bit is set, the MAC allows Jumbo frames of 9,018 bytes (9,022 bytes for VLAN tagged frames) without reporting a giant frame error in the receive frame status. 20 1 read-write IFG Inter-Frame Gap These bits control the minimum IFG between frames during transmission. - 000: 96 bit times - 001: 88 bit times - 010: 80 bit times - ... - 111: 40 bit times In the half-duplex mode, the minimum IFG can be configured only for 64 bit times (IFG = 100). Lower values are not considered. In the 1000-Mbps mode, the minimum IFG supported is 64 bit times (and above) in the GMAC-CORE configuration and 80 bit times (and above) in other configurations. When a JAM pattern is being transmitted because of backpressure activation, the MAC does not consider the minimum IFG. 17 3 read-write DCRS Disable Carrier Sense During Transmission When set high, this bit makes the MAC transmitter ignore the (G)MII CRS signal during frame transmission in the half-duplex mode. This request results in no errors generated because of Loss of Carrier or No Carrier during such transmission. When this bit is low, the MAC transmitter generates such errors because of Carrier Sense and can even abort the transmissions. 16 1 read-write PS Port Select This bit selects the Ethernet line speed. - 0: For 1000 Mbps operations - 1: For 10 or 100 Mbps operations In 10 or 100 Mbps operations, this bit, along with FES bit, selects the exact line speed. In the 10/100 Mbps-only (always 1) or 1000 Mbps-only (always 0) configurations, this bit is read-only with the appropriate value. In default 10/100/1000 Mbps configuration, this bit is R_W. The mac_portselect_o or mac_speed_o[1] signal reflects the value of this bit. 15 1 read-write FES Speed This bit selects the speed in the MII, RMII, SMII, RGMII, SGMII, or RevMII interface: - 0: 10 Mbps - 1: 100 Mbps This bit is reserved (RO) by default and is enabled only when the parameter SPEED_SELECT = Enabled. This bit generates link speed encoding when Bit 24 (TC) is set in the RGMII, SMII, or SGMII mode. This bit is always enabled for RGMII, SGMII, SMII, or RevMII interface. In configurations with RGMII, SGMII, SMII, or RevMII interface, this bit is driven as an output signal (mac_speed_o[0]) to reflect the value of this bit in the mac_speed_o signal. In configurations with RMII, MII, or GMII interface, you can optionally drive this bit as an output signal (mac_speed_o[0]) to reflect its value in the mac_speed_o signal. 14 1 read-write DO Disable Receive Own When this bit is set, the MAC disables the reception of frames when the phy_txen_o is asserted in the half-duplex mode. When this bit is reset, the MAC receives all packets that are given by the PHY while transmitting. This bit is not applicable if the MAC is operating in the full-duplex mode. This bit is reserved (RO with default value) if the MAC is configured for the full-duplex-only operation. 13 1 read-write LM Loopback Mode When this bit is set, the MAC operates in the loopback mode at GMII or MII. The (G)MII Receive clock input (clk_rx_i) is required for the loopback to work properly, because the Transmit clock is not looped-back internally. 12 1 read-write DM Duplex Mode When this bit is set, the MAC operates in the full-duplex mode where it can transmit and receive simultaneously. 11 1 read-write IPC Checksum Offload When this bit is set, the MAC calculates the 16-bit one’s complement of the one’s complement sum of all received Ethernet frame payloads. It also checks whether the IPv4 Header checksum (assumed to be bytes 25–26 or 29–30 (VLAN-tagged) of the received Ethernet frame) is correct for the received frame and gives the status in the receive status word. The MAC also appends the 16-bit checksum calculated for the IP header datagram payload (bytes after the IPv4 header) and appends it to the Ethernet frame transferred to the application (when Type 2 COE is deselected). When this bit is reset, this function is disabled. When Type 2 COE is selected, this bit, when set, enables the IPv4 header checksum checking and IPv4 or IPv6 TCP, UDP, or ICMP payload checksum checking. 10 1 read-write DR Disable Retry When this bit is set, the MAC attempts only one transmission. When a collision occurs on the GMII or MII interface, the MAC ignores the current frame transmission and reports a Frame Abort with excessive collision error in the transmit frame status. When this bit is reset, the MAC attempts retries based on the settings of the BL field (Bits [6:5]). 9 1 read-write LUD Link Up or Down This bit indicates whether the link is up or down during the transmission of configuration in the RGMII, SGMII, or SMII interface: - 0: Link Down - 1: Link Up 8 1 read-write ACS Automatic Pad or CRC Stripping When this bit is set, the MAC strips the Pad or FCS field on the incoming frames only if the value of the length field is less than 1,536 bytes. All received frames with length field greater than or equal to 1,536 bytes are passed to the application without stripping the Pad or FCS field. When this bit is reset, the MAC passes all incoming frames, without modifying them, to the Host. 7 1 read-write BL Back-Off Limit The Back-Off limit determines the random integer number (r) of slot time delays (4,096 bit times for 1000 Mbps and 512 bit times for 10/100 Mbps) for which the MAC waits before rescheduling a transmission attempt during retries after a collision. This bit is applicable only in the half-duplex mode and is reserved (RO) in the full-duplex-only configuration. - 00: k= min (n, 10) - 01: k = min (n, 8) - 10: k = min (n, 4) - 11: k = min (n, 1) where n = retransmission attempt. The random integer r takes the value in the range 0 ≤ r < 2k 5 2 read-write DC Deferral Check When this bit is set, the deferral check function is enabled in the MAC. The MAC issues a Frame Abort status, along with the excessive deferral error bit set in the transmit frame status, when the transmit state machine is deferred for more than 24,288 bit times in the 10 or 100 Mbps mode. If the MAC is configured for 1000 Mbps operation or if the Jumbo frame mode is enabled in the 10 or 100 Mbps mode, the threshold for deferral is 155,680 bits times. Deferral begins when the transmitter is ready to transmit, but it is prevented because of an active carrier sense signal (CRS) on GMII or MII. The defer time is not cumulative. For example, if the transmitter defers for 10,000 bit times because the CRS signal is active and then the CRS signal becomes inactive, the transmitter transmits and collision happens. Because of collision, the transmitter needs to back off and then defer again after back off completion. In such a scenario, the deferral timer is reset to 0 and it is restarted. 4 1 read-write TE Transmitter Enable When this bit is set, the transmit state machine of the MAC is enabled for transmission on the GMII or MII. When this bit is reset, the MAC transmit state machine is disabled after the completion of the transmission of the current frame, and does not transmit any further frames. 3 1 read-write RE Receiver Enable When this bit is set, the receiver state machine of the MAC is enabled for receiving frames from the GMII or MII. When this bit is reset, the MAC receive state machine is disabled after the completion of the reception of the current frame, and does not receive any further frames from the GMII or MII. 2 1 read-write PRELEN Preamble Length for Transmit frames These bits control the number of preamble bytes that are added to the beginning of every Transmit frame. The preamble reduction occurs only when the MAC is operating in the full-duplex mode. - 2'b00: 7 bytes of preamble - 2'b01: 5 bytes of preamble - 2'b10: 3 bytes of preamble - 2'b11: Reserved 0 2 read-write MACFF MAC Frame Filter 0x4 32 0x00000000 0x803087FF RA Receive All When this bit is set, the MAC Receiver module passes all received frames, irrespective of whether they pass the address filter or not, to the Application. The result of the SA or DA filtering is updated (pass or fail) in the corresponding bits in the Receive Status Word. When this bit is reset, the Receiver module passes only those frames to the Application that pass the SA or DA address filter. 31 1 read-write DNTU Drop non-TCP/UDP over IP Frames When set, this bit enables the MAC to drop the non-TCP or UDP over IP frames. The MAC forward only those frames that are processed by the Layer 4 filter. When reset, this bit enables the MAC to forward all non-TCP or UDP over IP frames. 21 1 read-write IPFE Layer 3 and Layer 4 Filter Enable When set, this bit enables the MAC to drop frames that do not match the enabled Layer 3 and Layer 4 filters. If Layer 3 or Layer 4 filters are not enabled for matching, this bit does not have any effect. When reset, the MAC forwards all frames irrespective of the match status of the Layer 3 and Layer 4 fields. 20 1 read-write VTFE VLAN Tag Filter Enable When set, this bit enables the MAC to drop VLAN tagged frames that do not match the VLAN Tag comparison. When reset, the MAC forwards all frames irrespective of the match status of the VLAN Tag. 15 1 read-write HPF Hash or Perfect Filter When this bit is set, it configures the address filter to pass a frame if it matches either the perfect filtering or the hash filtering as set by the HMC or HUC bits. When this bit is low and the HUC or HMC bit is set, the frame is passed only if it matches the Hash filter. 10 1 read-write SAF Source Address Filter Enable When this bit is set, the MAC compares the SA field of the received frames with the values programmed in the enabled SA registers. If the comparison fails, the MAC drops the frame. When this bit is reset, the MAC forwards the received frame to the application with updated SAF bit of the Rx Status depending on the SA address comparison. 9 1 read-write SAIF SA Inverse Filtering When this bit is set, the Address Check block operates in inverse filtering mode for the SA address comparison. The frames whose SA matches the SA registers are marked as failing the SA Address filter. When this bit is reset, frames whose SA does not match the SA registers are marked as failing the SA Address filter. 8 1 read-write PCF Pass Control Frames These bits control the forwarding of all control frames (including unicast and multicast Pause frames). - 00: MAC filters all control frames from reaching the application. - 01: MAC forwards all control frames except Pause frames to application even if they fail the Address filter. - 10: MAC forwards all control frames to application even if they fail the Address Filter. - 11: MAC forwards control frames that pass the Address Filter. The following conditions should be true for the Pause frames processing: - Condition 1: The MAC is in the full-duplex mode and flow control is enabled by setting Bit 2 (RFE) of Register 6 (Flow Control Register) to 1. - Condition 2: The destination address (DA) of the received frame matches the special multicast address or the MAC Address 0 when Bit 3 (UP) of the Register 6 (Flow Control Register) is set. - Condition 3: The Type field of the received frame is 0x8808 and the OPCODE field is 0x0001. Note: This field should be set to 01 only when the Condition 1 is true, that is, the MAC is programmed to operate in the full-duplex mode and the RFE bit is enabled. Otherwise, the Pause frame filtering may be inconsistent. When Condition 1 is false, the Pause frames are considered as generic control frames. Therefore, to pass all control frames (including Pause frames) when the full-duplex mode and flow control is not enabled, you should set the PCF field to 10 or 11 (as required by the application). 6 2 read-write DBF Disable Broadcast Frames When this bit is set, the AFM module blocks all incoming broadcast frames. In addition, it overrides all other filter settings. When this bit is reset, the AFM module passes all received broadcast frames. 5 1 read-write PM Pass All Multicast When set, this bit indicates that all received frames with a multicast destination address (first bit in the destination address field is '1') are passed. When reset, filtering of multicast frame depends on HMC bit. 4 1 read-write DAIF DA Inverse Filtering When this bit is set, the Address Check block operates in inverse filtering mode for the DA address comparison for both unicast and multicast frames. When reset, normal filtering of frames is performed. 3 1 read-write HMC Hash Multicast When set, the MAC performs destination address filtering of received multicast frames according to the hash table. When reset, the MAC performs a perfect destination address filtering for multicast frames, that is, it compares the DA field with the values programmed in DA registers. 2 1 read-write HUC Hash Unicast When set, the MAC performs destination address filtering of unicast frames according to the hash table. When reset, the MAC performs a perfect destination address filtering for unicast frames, that is, it compares the DA field with the values programmed in DA registers. 1 1 read-write PR Promiscuous Mode When this bit is set, the Address Filter module passes all incoming frames irrespective of the destination or source address. The SA or DA Filter Fails status bits of the Receive Status Word are always cleared when PR is set. 0 1 read-write HASH_H Hash Table High Register 0x8 32 0x00000000 0xFFFFFFFF HTH Hash Table High This field contains the upper 32 bits of the Hash table. 0 32 read-write HASH_L Hash Table Low Register 0xc 32 0x00000000 0xFFFFFFFF HTL Hash Table Low This field contains the lower 32 bits of the Hash table. 0 32 read-write GMII_ADDR GMII Address Register 0x10 32 0x00000000 0x0000FFFF PA Physical Layer Address This field indicates which of the 32 possible PHY devices are being accessed. For RevMII, this field gives the PHY Address of the RevMII module. 11 5 read-write GR GMII Register These bits select the desired GMII register in the selected PHY device. For RevMII, these bits select the desired CSR register in the RevMII Registers set. 6 5 read-write CR CSR Clock Range The CSR Clock Range selection determines the frequency of the MDC clock according to the CSR clock frequency used in your design. The CSR clock corresponding to different GMAC configurations is given in Table 9-2 on page 564. The suggested range of CSR clock frequency applicable for each value (when Bit[5] = 0) ensures that the MDC clock is approximately between the frequency range 1.0 MHz–2.5 MHz. - 0000: The CSR clock frequency is 60–100 MHz and the MDC clock frequency is CSR clock/42. - 0001: The CSR clock frequency is 100–150 MHz and the MDC clock frequency is CSR clock/62. - 0010: The CSR clock frequency is 20–35 MHz and the MDC clock frequency is CSR clock/16. - 0011: The CSR clock frequency is 35–60 MHz and the MDC clock frequency is CSR clock/26. - 0100: The CSR clock frequency is 150–250 MHz and the MDC clock frequency is CSR clock/102. - 0101: The CSR clock frequency is 250–300 MHz and the MDC clock is CSR clock/124. - 0110, 0111: Reserved When Bit 5 is set, you can achieve higher frequency of the MDC clock than the frequency limit of 2.5 MHz (specified in the IEEE Std 802.3) and program a clock divider of lower value. For example, when CSR clock is of 100 MHz frequency and you program these bits as 1010, then the resultant MDC clock is of 12.5 MHz which is outside the limit of IEEE 802.3 specified range. Program the following values only if the interfacing chips support faster MDC clocks. - 1000: CSR clock/4 - 1001: CSR clock/6 - 1010: CSR clock/8 - 1011: CSR clock/10 - 1100: CSR clock/12 - 1101: CSR clock/14 - 1110: CSR clock/16 - 1111: CSR clock/18 These bits are not used for accessing RevMII. These bits are read-only if the RevMII interface is selected as single PHY interface. 2 4 read-write GW GMII Write When set, this bit indicates to the PHY or RevMII that this is a Write operation using the GMII Data register. If this bit is not set, it indicates that this is a Read operation, that is, placing the data in the GMII Data register. 1 1 read-write GB GMII Busy This bit should read logic 0 before writing to Register 4 and Register 5. During a PHY or RevMII register access, the software sets this bit to 1’b1 to indicate that a Read or Write access is in progress. Register 5 is invalid until this bit is cleared by the MAC. Therefore, Register 5 (GMII Data) should be kept valid until the MAC clears this bit during a PHY Write operation. Similarly for a read operation, the contents of Register 5 are not valid until this bit is cleared. The subsequent read or write operation should happen only after the previous operation is complete. Because there is no acknowledgment from the PHY to MAC after a read or write operation is completed, there is no change in the functionality of this bit even when the PHY is not present. 0 1 read-write GMII_DATA GMII Data Register 0x14 32 0x00000000 0x0000FFFF GD GMII Data This field contains the 16-bit data value read from the PHY or RevMII after a Management Read operation or the 16-bit data value to be written to the PHY or RevMII before a Management Write operation. 0 16 read-write FLOWCTRL Flow Control Register 0x18 32 0x00000000 0xFFFF00BF PT Pause Time This field holds the value to be used in the Pause Time field in the transmit control frame. If the Pause Time bits is configured to be double-synchronized to the (G)MII clock domain, then consecutive writes to this register should be performed only after at least four clock cycles in the destination clock domain. 16 16 read-write DZPQ Disable Zero-Quanta Pause When this bit is set, it disables the automatic generation of the Zero-Quanta Pause frames on the de-assertion of the flow-control signal from the FIFO layer (MTL or external sideband flow control signal sbd_flowctrl_i/mti_flowctrl_i). When this bit is reset, normal operation with automatic Zero-Quanta Pause frame generation is enabled. 7 1 read-write PLT Pause Low Threshold This field configures the threshold of the Pause timer at which the input flow control signal mti_flowctrl_i (or sbd_flowctrl_i) is checked for automatic retransmission of the Pause frame. The threshold values should be always less than the Pause Time configured in Bits[31:16]. For example, if PT = 100H (256 slot-times), and PLT = 01, then a second Pause frame is automatically transmitted if the mti_flowctrl_i signal is asserted at 228 (256 – 28) slot times after the first Pause frame is transmitted. The following list provides the threshold values for different values: - 00: The threshold is Pause time minus 4 slot times (PT – 4 slot times). - 01: The threshold is Pause time minus 28 slot times (PT – 28 slot times). - 10: The threshold is Pause time minus 144 slot times (PT – 144 slot times). - 11: The threshold is Pause time minus 256 slot times (PT – 256 slot times). The slot time is defined as the time taken to transmit 512 bits (64 bytes) on the GMII or MII interface. 4 2 read-write UP Unicast Pause Frame Detect A pause frame is processed when it has the unique multicast address specified in the IEEE Std 802.3. When this bit is set, the MAC can also detect Pause frames with unicast address of the station. This unicast address should be as specified in the MAC Address0 High Register and MAC Address0 Low Register. When this bit is reset, the MAC only detects Pause frames with unique multicast address. 3 1 read-write RFE Receive Flow Control Enable When this bit is set, the MAC decodes the received Pause frame and disables its transmitter for a specified (Pause) time. When this bit is reset, the decode function of the Pause frame is disabled. 2 1 read-write TFE Transmit Flow Control Enable In the full-duplex mode, when this bit is set, the MAC enables the flow control operation to transmit Pause frames. When this bit is reset, the flow control operation in the MAC is disabled, and the MAC does not transmit any Pause frames. In the half-duplex mode, when this bit is set, the MAC enables the backpressure operation. When this bit is reset, the backpressure feature is disabled. 1 1 read-write FCB_BPA Flow Control Busy or Backpressure Activate This bit initiates a Pause frame in the full-duplex mode and activates the backpressure function in the half-duplex mode if the TFE bit is set. In the full-duplex mode, this bit should be read as 1'b0 before writing to the Flow Control register. To initiate a Pause frame, the Application must set this bit to 1'b1. During a transfer of the Control Frame, this bit continues to be set to signify that a frame transmission is in progress. After the completion of Pause frame transmission, the MAC resets this bit to 1'b0. The Flow Control register should not be written to until this bit is cleared. In the half-duplex mode, when this bit is set (and TFE is set), then backpressure is asserted by the MAC. During backpressure, when the MAC receives a new frame, the transmitter starts sending a JAM pattern resulting in a collision. This control register bit is logically ORed with the mti_flowctrl_i input signal for the backpressure function. When the MAC is configured for the full-duplex mode, the BPA is automatically disabled. 0 1 read-write VLAN_TAG VLAN Tag Register 0x1c 32 0x00000000 0x000FFFFF VTHM VLAN Tag Hash Table Match Enable When set, the most significant four bits of the VLAN tag’s CRC are used to index the content of Register 354 (VLAN Hash Table Register). A value of 1 in the VLAN Hash Table register, corresponding to the index, indicates that the frame matched the VLAN hash table. When Bit 16 (ETV) is set, the CRC of the 12-bit VLAN Identifier (VID) is used for comparison whereas when ETV is reset, the CRC of the 16-bit VLAN tag is used for comparison. When reset, the VLAN Hash Match operation is not performed. 19 1 read-write ESVL Enable S-VLAN When this bit is set, the MAC transmitter and receiver also consider the S-VLAN (Type = 0x88A8) frames as valid VLAN tagged frames. 18 1 read-write VTIM VLAN Tag Inverse Match Enable When set, this bit enables the VLAN Tag inverse matching. The frames that do not have matching VLAN Tag are marked as matched. When reset, this bit enables the VLAN Tag perfect matching. The frames with matched VLAN Tag are marked as matched. 17 1 read-write ETV Enable 12-Bit VLAN Tag Comparison When this bit is set, a 12-bit VLAN identifier is used for comparing and filtering instead of the complete 16-bit VLAN tag. Bits [11:0] of VLAN tag are compared with the corresponding field in the received VLAN-tagged frame. Similarly, when enabled, only 12 bits of the VLAN tag in the received frame are used for hash-based VLAN filtering. When this bit is reset, all 16 bits of the 15th and 16th bytes of the received VLAN frame are used for comparison and VLAN hash filtering. 16 1 read-write VL VLAN Tag Identifier for Receive Frames This field contains the 802.1Q VLAN tag to identify the VLAN frames and is compared to the 15th and 16th bytes of the frames being received for VLAN frames. The following list describes the bits of this field: - Bits [15:13]: User Priority - Bit 12: Canonical Format Indicator (CFI) or Drop Eligible Indicator (DEI) - Bits[11:0]: VLAN tag’s VLAN Identifier (VID) field When the ETV bit is set, only the VID (Bits[11:0]) is used for comparison. If VL (VL[11:0] if ETV is set) is all zeros, the MAC does not check the fifteenth and 16th bytes for VLAN tag comparison, and declares all frames with a Type field value of 0x8100 or 0x88a8 as VLAN frames. 0 16 read-write RWKFRMFILT Remote Wake-Up Frame Filter Register 0x28 32 0x00000000 0xFFFFFFFF WKUPFRMFILT This is the address through which the application writes or reads the remote wake-up frame filter registers (wkupfmfilter_reg). The wkupfmfilter_reg register is a pointer to eight wkupfmfilter_reg registers. The wkupfmfilter_reg register is loaded by sequentially loading the eight register values. Eight sequential writes to this address (0x0028) write all wkupfmfilter_reg registers. Similarly, eight sequential reads from this address (0x0028) read all wkupfmfilter_reg registers 0 32 read-write PMT_CSR PMT Control and Status Register 0x2c 32 0x00000000 0x9F000267 RWKFILTRST Remote Wake-Up Frame Filter Register Pointer Reset When this bit is set, it resets the remote wake-up frame filter register pointer to 3’b000. It is automatically cleared after 1 clock cycle. 31 1 read-write RWKPTR Remote Wake-up FIFO Pointer This field gives the current value (0 to 31) of the Remote Wake-up Frame filter register pointer. When the value of this pointer is equal to 7, 15, 23 or 31, the contents of the Remote Wake-up Frame Filter Register are transferred to the clk_rx_i domain when a write occurs to that register. The maximum value of the pointer is 7, 15, 23 and 31 respectively depending on the number of Remote Wakeup Filters selected during configuration. 24 5 read-write GLBLUCAST Global Unicast When set, enables any unicast packet filtered by the MAC (DAF) address recognition to be a remote wake-up frame. 9 1 read-write RWKPRCVD Remote Wake-Up Frame Received When set, this bit indicates the power management event is generated because of the reception of a remote wake-up frame. This bit is cleared by a Read into this register. 6 1 read-write MGKPRCVD Magic Packet Received When set, this bit indicates that the power management event is generated because of the reception of a magic packet. This bit is cleared by a Read into this register. 5 1 read-write RWKPKTEN Remote Wake-Up Frame Enable When set, enables generation of a power management event because of remote wake-up frame reception. 2 1 read-write MGKPKTEN Magic Packet Enable When set, enables generation of a power management event because of magic packet reception. 1 1 read-write PWRDWN Power Down When set, the MAC receiver drops all received frames until it receives the expected magic packet or remote wake-up frame. This bit is then self-cleared and the power-down mode is disabled. The Software can also clear this bit before the expected magic packet or remote wake-up frame is received. The frames, received by the MAC after this bit is cleared, are forwarded to the application. This bit must only be set when the Magic Packet Enable, Global Unicast, or Remote Wake-Up Frame Enable bit is set high. Note: You can gate-off the CSR clock during the power-down mode. However, when the CSR clock is gated-off, you cannot perform any read or write operations on this register. Therefore, the Software cannot clear this bit. 0 1 read-write LPI_CSR LPI Control and Status Register 0x30 32 0x00000000 0x000F030F LPITXA LPI TX Automate This bit controls the behavior of the MAC when it is entering or coming out of the LPI mode on the transmit side. This bit is not functional in the GMAC-CORE configuration in which the Tx clock gating is done during the LPI mode. If the LPITXA and LPIEN bits are set to 1, the MAC enters the LPI mode only after all outstanding frames (in the core) and pending frames (in the application interface) have been transmitted. The MAC comes out of the LPI mode when the application sends any frame for transmission or the application issues a TX FIFO Flush command. In addition, the MAC automatically clears the LPIEN bit when it exits the LPI state. If TX FIFO Flush is set in Bit 20 of Register 6 (Operation Mode Register), when the MAC is in the LPI mode, the MAC exits the LPI mode. When this bit is 0, the LPIEN bit directly controls behavior of the MAC when it is entering or coming out of the LPI mode. 19 1 read-write PLSEN PHY Link Status Enable This bit enables the link status received on the RGMII, SGMII, or SMII receive paths to be used for activating the LPI LS TIMER. When set, the MAC uses the link-status bits of Register 54 (SGMII/RGMII/SMII Control and Status Register) and Bit 17 (PLS) for the LPI LS Timer trigger. When cleared, the MAC ignores the link-status bits of Register 54 and takes only the PLS bit. This bit is RO and reserved if you have not selected the RGMII, SGMII, or SMII PHY interface. 18 1 read-write PLS PHY Link Status This bit indicates the link status of the PHY. The MAC Transmitter asserts the LPI pattern only when the link status is up (okay) at least for the time indicated by the LPI LS TIMER. When set, the link is considered to be okay (up) and when reset, the link is considered to be down. 17 1 read-write LPIEN LPI Enable When set, this bit instructs the MAC Transmitter to enter the LPI state. When reset, this bit instructs the MAC to exit the LPI state and resume normal transmission. This bit is cleared when the LPITXA bit is set and the MAC exits the LPI state because of the arrival of a new packet for transmission. 16 1 read-write RLPIST Receive LPI State When set, this bit indicates that the MAC is receiving the LPI pattern on the GMII or MII interface. 9 1 read-write TLPIST Transmit LPI State When set, this bit indicates that the MAC is transmitting the LPI pattern on the GMII or MII interface. 8 1 read-write RLPIEX Receive LPI Exit When set, this bit indicates that the MAC Receiver has stopped receiving the LPI pattern on the GMII or MII interface, exited the LPI state, and resumed the normal reception. This bit is cleared by a read into this register. Note: This bit may not get set if the MAC stops receiving the LPI pattern for a very short duration, such as, less than 3 clock cycles of CSR clock. 3 1 read-write RLPIEN Receive LPI Entry When set, this bit indicates that the MAC Receiver has received an LPI pattern and entered the LPI state. This bit is cleared by a read into this register. Note: This bit may not get set if the MAC stops receiving the LPI pattern for a very short duration, such as, less than 3 clock cycles of CSR clock. 2 1 read-write TLPIEX Transmit LPI Exit When set, this bit indicates that the MAC transmitter has exited the LPI state after the user has cleared the LPIEN bit and the LPI TW Timer has expired. This bit is cleared by a read into this register. 1 1 read-write TLPIEN Transmit LPI Entry When set, this bit indicates that the MAC Transmitter has entered the LPI state because of the setting of the LPIEN bit. This bit is cleared by a read into this register. 0 1 read-write LPI_TCR LPI Timers Control Register 0x34 32 0x00000000 0x03FFFFFF LST LPI LS TIMER This field specifies the minimum time (in milliseconds) for which the link status from the PHY should be up (OKAY) before the LPI pattern can be transmitted to the PHY. The MAC does not transmit the LPI pattern even when the LPIEN bit is set unless the LPI LS Timer reaches the programmed terminal count. The default value of the LPI LS Timer is 1000 (1 sec) as defined in the IEEE standard. 16 10 read-write TWT LPI TW TIMER This field specifies the minimum time (in microseconds) for which the MAC waits after it stops transmitting the LPI pattern to the PHY and before it resumes the normal transmission. The TLPIEX status bit is set after the expiry of this timer. 0 16 read-write INTR_STATUS Interrupt Status Register 0x38 32 0x00000000 0x00000EFF GPIIS GPI Interrupt Status When the GPIO feature is enabled, this bit is set when any active event (LL or LH) occurs on the GPIS field (Bits [3:0]) of Register 56 (General Purpose IO Register) and the corresponding GPIE bit is enabled. This bit is cleared on reading lane 0 (GPIS) of Register 56 (General Purpose IO Register). When the GPIO feature is not enabled, this bit is reserved. 11 1 read-only LPIIS LPI Interrupt Status When the Energy Efficient Ethernet feature is enabled, this bit is set for any LPI state entry or exit in the MAC Transmitter or Receiver. This bit is cleared on reading Bit 0 of Register 12 (LPI Control and Status Register). In all other modes, this bit is reserved. 10 1 read-only TSIS Timestamp Interrupt Status When the Advanced Timestamp feature is enabled, this bit is set when any of the following conditions is true: - The system time value equals or exceeds the value specified in the Target Time High and Low registers. - There is an overflow in the seconds register. - The Auxiliary snapshot trigger is asserted. This bit is cleared on reading Bit 0 of Register 458 (Timestamp Status Register). 9 1 read-only MMCRXIPIS MMC Receive Checksum Offload Interrupt Status This bit is set high when an interrupt is generated in the MMC Receive Checksum Offload Interrupt Register. This bit is cleared when all the bits in this interrupt register are cleared. 7 1 read-only MMCTXIS MMC Transmit Interrupt Status This bit is set high when an interrupt is generated in the MMC Transmit Interrupt Register.

This bit is cleared when all the bits in this interrupt register are cleared. 5 1 read-only MMCIS MMC Interrupt Status This bit is set high when any of the Bits [7:5] is set high and cleared only when all of these bits are low. 4 1 read-only PMTIS PMT Interrupt Status This bit is set when a magic packet or remote wake-up frame is received in the power-down mode (see Bits 5 and 6 in the PMT Control and Status Register). This bit is cleared when both Bits[6:5] are cleared because of a read operation to the PMT Control and Status register. 3 1 read-only PCSANCIS PCS Auto-Negotiation Complete This bit is set when the Auto-negotiation is completed in the TBI, RTBI, or SGMII PHY interface (Bit 5 in Register 49 (AN Status Register)). This bit is cleared when you perform a read operation to the AN Status register. 2 1 read-only PCSLCHGIS PCS Link Status Changed This bit is set because of any change in Link Status in the TBI, RTBI, or SGMII PHY interface (Bit 2 in Register 49 (AN Status Register)). This bit is cleared when you perform a read operation on the AN Status register. 1 1 read-only RGSMIIIS RGMII or SMII Interrupt Status This bit is set because of any change in value of the Link Status of RGMII or SMII interface (Bit 3 in Register 54 (SGMII/RGMII/SMII Control and Status Register)). This bit is cleared when you perform a read operation on the SGMII/RGMII/SMII Control and Status Register. 0 1 read-only INTR_MASK Interrupt Mask Register 0x3c 32 0x00000000 0x0000060F LPIIM LPI Interrupt Mask When set, this bit disables the assertion of the interrupt signal because of the setting of the LPI Interrupt Status bit in Register 14 (Interrupt Status Register). 10 1 read-write TSIM Timestamp Interrupt Mask When set, this bit disables the assertion of the interrupt signal because of the setting of Timestamp Interrupt Status bit in Register 14 (Interrupt Status Register). 9 1 read-write PMTIM PMT Interrupt Mask When set, this bit disables the assertion of the interrupt signal because of the setting of PMT Interrupt Status bit in Register 14 (Interrupt Status Register). 3 1 read-write PCSANCIM PCS AN Completion Interrupt Mask When set, this bit disables the assertion of the interrupt signal because of the setting of PCS Auto-negotiation complete bit in Register 14 (Interrupt Status Register). 2 1 read-write PCSLCHGIM PCS Link Status Interrupt Mask When set, this bit disables the assertion of the interrupt signal because of the setting of the PCS Link-status changed bit in Register 14 (Interrupt Status Register). 1 1 read-write RGSMIIIM RGMII or SMII Interrupt Mask When set, this bit disables the assertion of the interrupt signal because of the setting of the RGMII or SMII Interrupt Status bit in Register 14 (Interrupt Status Register). 0 1 read-write MAC_ADDR_0_HIGH MAC Address 0 High Register 0x40 32 0x00000000 0x8000FFFF AE Address Enable This bit is RO. The bit value is fixed at 1. 31 1 read-only ADDRHI MAC Address0 [47:32] This field contains the upper 16 bits (47:32) of the first 6-byte MAC address. The MAC uses this field for filtering the received frames and inserting the MAC address in the Transmit Flow Control (Pause) Frames. 0 16 read-write MAC_ADDR_0_LOW MAC Address 0 Low Register 0x44 32 0x00000000 0xFFFFFFFF ADDRLO MAC Address0 [31:0] This field contains the lower 32 bits of the first 6-byte MAC address. This is used by the MAC for filtering the received frames and inserting the MAC address in the Transmit Flow Control (Pause) Frames. 0 32 read-write 4 0x8 1,2,3,4 MAC_ADDR[%s] no description available 0x48 HIGH MAC Address High Register 0x0 32 0x00000000 0xFF00FFFF AE Address Enable When this bit is set, the address filter module uses the second MAC address for perfect filtering. When this bit is reset, the address filter module ignores the address for filtering. 31 1 read-write SA Source Address When this bit is set, the MAC Address1[47:0] is used to compare with the SA fields of the received frame. When this bit is reset, the MAC Address1[47:0] is used to compare with the DA fields of the received frame. 30 1 read-write MBC Mask Byte Control These bits are mask control bits for comparison of each of the MAC Address bytes. When set high, the MAC does not compare the corresponding byte of received DA or SA with the contents of MAC Address1 registers. Each bit controls the masking of the bytes as follows: - Bit 29: Register 18[15:8] - Bit 28: Register 18[7:0] - Bit 27: Register 19[31:24] - ... - Bit 24: Register 19[7:0] You can filter a group of addresses (known as group address filtering) by masking one or more bytes of the address. 24 6 read-write ADDRHI MAC Address1 [47:32] This field contains the upper 16 bits (47:32) of the second 6-byte MAC address. 0 16 read-write LOW MAC Address Low Register 0x4 32 0x00000000 0xFFFFFFFF ADDRLO MAC Address1 [31:0] This field contains the lower 32 bits of the second 6-byte MAC address. The content of this field is undefined until loaded by the Application after the initialization process. 0 32 read-write XMII_CSR SGMII/RGMII/SMII Control and Status Register 0xd8 32 0x00000000 0x0000003F FALSCARDET False Carrier Detected This bit indicates whether the SMII PHY detected false carrier (1'b1). This bit is reserved when the MAC is configured for the SGMII or RGMII PHY interface. 5 1 read-write JABTO Jabber Timeout This bit indicates whether there is jabber timeout error (1'b1) in the received frame. This bit is reserved when the MAC is configured for the SGMII or RGMII PHY interface. 4 1 read-write LNKSTS Link Status This bit indicates whether the link between the local PHY and the remote PHY is up or down. It gives the status of the link between the SGMII of MAC and the SGMII of the local PHY. The status bits are received from the local PHY during ANEG betweent he MAC and PHY on the SGMII link. 3 1 read-write LNKSPEED Link Speed This bit indicates the current speed of the link: - 00: 2.5 MHz - 01: 25 MHz - 10: 125 MHz Bit 2 is reserved when the MAC is configured for the SMII PHY interface. 1 2 read-write LNKMOD Link Mode This bit indicates the current mode of operation of the link: - 1’b0: Half-duplex mode - 1’b1: Full-duplex mode 0 1 read-write WDOG_WTO Watchdog Timeout Register 0xdc 32 0x00000000 0x00013FFF PWE Programmable Watchdog Enable When this bit is set and Bit 23 (WD) of Register 0 (MAC Configuration Register) is reset, the WTO field (Bits[13:0]) is used as watchdog timeout for a received frame. When this bit is cleared, the watchdog timeout for a received frame is controlled by the setting of Bit 23 (WD) and Bit 20 (JE) in Register 0 (MAC Configuration Register). 16 1 read-write WTO Watchdog Timeout When Bit 16 (PWE) is set and Bit 23 (WD) of Register 0 (MAC Configuration Register) is reset, this field is used as watchdog timeout for a received frame. If the length of a received frame exceeds the value of this field, such frame is terminated and declared as an error frame. Note: When Bit 16 (PWE) is set, the value in this field should be more than 1,522 (0x05F2). Otherwise, the IEEE Std 802.3-specified valid tagged frames are declared as error frames and are dropped. 0 14 read-write mmc_cntrl MMC Control establishes the operating mode of MMC. 0x100 32 0x00000000 0x0000013F UCDBC Update MMC Counters for Dropped Broadcast Frames When set, the MAC updates all related MMC Counters for Broadcast frames that are dropped because of the setting of Bit 5 (DBF) of Register 1 (MAC Frame Filter). When reset, the MMC Counters are not updated for dropped Broadcast frames. 8 1 read-write CNTPRSTLVL Full-Half Preset When this bit is low and Bit 4 is set, all MMC counters get preset to almost-half value. All octet counters get preset to 0x7FFF_F800 (half - 2KBytes) and all frame-counters gets preset to 0x7FFF_FFF0 (half - 16). When this bit is high and Bit 4 is set, all MMC counters get preset to almost-full value. All octet counters get preset to 0xFFFF_F800 (full - 2KBytes) and all frame-counters gets preset to 0xFFFF_FFF0 (full - 16). For 16-bit counters, the almost-half preset values are 0x7800 and 0x7FF0 for the respective octet and frame counters. Similarly, the almost-full preset values for the 16-bit counters are 0xF800 and 0xFFF0. 5 1 read-write CNTPRST Counters Preset When this bit is set, all counters are initialized or preset to almost full or almost half according to Bit 5. This bit is cleared automatically after 1 clock cycle. This bit, along with Bit 5, is useful for debugging and testing the assertion of interrupts because of MMC counter becoming half-full or full. 4 1 read-write CNTFREEZ MMC Counter Freeze When this bit is set, it freezes all MMC counters to their current value. Until this bit is reset to 0, no MMC counter is updated because of any transmitted or received frame. If any MMC counter is read with the Reset on Read bit set, then that counter is also cleared in this mode. 3 1 read-write RSTONRD Reset on Read When this bit is set, the MMC counters are reset to zero after Read (self-clearing after reset). The counters are cleared when the least significant byte lane (Bits[7:0]) is read. 2 1 read-write CNTSTOPRO Counter Stop Rollover When this bit is set, the counter does not roll over to zero after reaching the maximum value. 1 1 read-write CNTRST Counters Reset When this bit is set, all counters are reset.

Programming the PPSCMD field to 010 or 011, instructs the MAC to synchronize the Target Time Registers to the PTP clock domain. The MAC clears this bit after synchronizing the Target Time Registers to the PTP clock domain The application must not update the Target Time Registers when this bit is read as 1. Otherwise, the synchronization of the previous programmed time gets corrupted. This bit is reserved when the Enable Flexible Pulse-Per-Second Output feature is not selected. 31 1 read-write TTSLO Target Timestamp Low Register This register stores the time in (signed) nanoseconds. When the value of the timestamp matches the both Target Timestamp registers, then based on the TRGTMODSEL0 field (Bits [6:5]) in Register 459 (PPS Control Register), the MAC starts or stops the PPS signal output and generates an interrupt (if enabled). This value should not exceed 0x3B9A_C9FF when Bit 9 (TSCTRLSSR) is set in Register 448 (Timestamp Control Register). The actual start or stop time of the PPS signal output may have an error margin up to one unit of sub-second increment value. 0 31 read-write SYSTM_H_SEC System Time - Higher Word Seconds Register 0x724 32 0x00000000 0x0000FFFF TSHWR Timestamp Higher Word Register This field contains the most significant 16-bits of the timestamp seconds value.

This bit is valid only if the Add IEEE 1588 Auxiliary Snapshot option is selected during core configuration. 24 1 read-only ATSSTN Auxiliary Timestamp Snapshot Trigger Identifier These bits identify the Auxiliary trigger inputs for which the timestamp available in the Auxiliary Snapshot Register is applicable. When more than one bit is set at the same time, it means that corresponding auxiliary triggers were sampled at the same clock.

The actual clock is of different frequency that gets synchronized every second. For example: - When PPSCTRL = 0001, the PPS (1 Hz) has a low period of 537 ms and a high period of 463 ms - When PPSCTRL = 0010, the PPS (2 Hz) is a sequence of: - One clock of 50 percent duty cycle and 537 ms period - Second clock of 463 ms period (268 ms low and 195 ms high) - When PPSCTRL = 0011, the PPS (4 Hz) is a sequence of: - Three clocks of 50 percent duty cycle and 268 ms period - Fourth clock of 195 ms period (134 ms low and 61 ms high) PPSCMD0: Flexible PPS0 Output Control 0000: No Command 0001: START Single Pulse This command generates single pulse rising at the start point defined in Target Time Registers and of a duration defined in the PPS0 Width Register. 0010: START Pulse Train This command generates the train of pulses rising at the start point defined in the Target Time Registers and of a duration defined in the PPS0 Width Register and repeated at interval defined in the PPS Interval Register. By default, the PPS pulse train is free-running unless stopped by ‘STOP Pulse train at time’ or ‘STOP Pulse Train immediately’ commands. 0011: Cancel START This command cancels the START Single Pulse and START Pulse Train commands if the system time has not crossed the programmed start time. 0100: STOP Pulse train at time This command stops the train of pulses initiated by the START Pulse Train command (PPSCMD = 0010) after the time programmed in the Target Time registers elapses. 0101: STOP Pulse Train immediately This command immediately stops the train of pulses initiated by the START Pulse Train command (PPSCMD = 0010). 0110: Cancel STOP Pulse train This command cancels the STOP pulse train at time command if the programmed stop time has not elapsed.

You need to program one value less than the required interval. For example, if the PTP reference clock is 50 MHz (period of 20ns), and desired interval between rising edges of PPS0 signal output is 100ns (that is, five units of sub-second increment value), then you should program value 4 (5 – 1) in this register. 0 32 read-write PPS0_WIDTH PPS0 Width Register 0x764 32 0x00000000 0xFFFFFFFF PPSWIDTH PPS0 Output Signal Width These bits store the width between the rising edge and corresponding falling edge of the PPS0 signal output in terms of units of sub-second increment value. You need to program one value less than the required interval. For example, if PTP reference clock is 50 MHz (period of 20ns), and desired width between the rising and corresponding falling edges of PPS0 signal output is 80ns (that is, four units of sub-second increment value), then you should program value 3 (4 – 1) in this register. 0 32 read-write 3 0x20 1,2,3 PPS[%s] no description available 0x780 TGTTM_SEC PPS Target Time Seconds Register 0x0 32 0x00000000 0xFFFFFFFF TSTRH1 PPS1 Target Time Seconds Register This register stores the time in seconds. When the timestamp value matches or exceeds both Target Timestamp registers, then based on Bits [14:13], TRGTMODSEL1, of Register 459 (PPS Control Register), the MAC starts or stops the PPS signal output and generates an interrupt (if enabled). 0 32 read-write TGTTM_NSEC PPS Target Time Nanoseconds Register 0x4 32 0x00000000 0xFFFFFFFF TRGTBUSY1 PPS1 Target Time Register Busy The MAC sets this bit when the PPSCMD1 field (Bits [10:8]) in Register 459 (PPS Control Register) is programmed to 010 or 011. Programming the PPSCMD1 field to 010 or 011 instructs the MAC to synchronize the Target Time Registers to the PTP clock domain. The MAC clears this bit after synchronizing the Target Time Registers to the PTP clock domain The application must not update the Target Time Registers when this bit is read as 1. Otherwise, the synchronization of the previous programmed time gets corrupted. 31 1 read-write TTSL1 Target Time Low for PPS1 Register This register stores the time in (signed) nanoseconds. When the value of the timestamp matches the both Target Timestamp registers, then based on the TRGTMODSEL1 field (Bits [14:13]) in Register 459 (PPS Control Register), the MAC starts or stops the PPS signal output and generates an interrupt (if enabled). This value should not exceed 0x3B9A_C9FF when Bit 9 (TSCTRLSSR) is set in Register 448 (Timestamp Control Register). The actual start or stop time of the PPS signal output may have an error margin up to one unit of sub-second increment value. 0 31 read-write INTERVAL PPS Interval Register 0x8 32 0x00000000 0xFFFFFFFF PPSINT PPS1 Output Signal Interval These bits store the interval between the rising edges of PPS1 signal output in terms of units of sub-second increment value. You need to program one value less than the required interval. For example, if the PTP reference clock is 50 MHz (period of 20ns), and desired interval between rising edges of PPS1 signal output is 100ns (that is, five units of sub-second increment value), then you should program value 4 (5 – 1) in this register. 0 32 read-write WIDTH PPS Width Register 0xc 32 0x00000000 0xFFFFFFFF PPSWIDTH PPS1 Output Signal Width These bits store the width between the rising edge and corresponding falling edge of the PPS1 signal output in terms of units of sub-second increment value. You need to program one value less than the required interval. For example, if PTP reference clock is 50 MHz (period of 20ns), and desired width between the rising and corresponding falling edges of PPS1 signal output is 80ns (that is, four units of sub-second increment value), then you should program value 3 (4 – 1) in this register. 0 32 read-write DMA_BUS_MODE Bus Mode Register 0x1000 32 0x00000000 0xBFFFFFFF RIB Rebuild INCRx Burst When this bit is set high and the AHB master gets an EBT (Retry, Split, or Losing bus grant), the AHB master interface rebuilds the pending beats of any burst transfer initiated with INCRx. The AHB master interface rebuilds the beats with a combination of specified bursts with INCRx and SINGLE. By default, the AHB master interface rebuilds pending beats of an EBT with an unspecified (INCR) burst. 31 1 read-write PRWG Channel Priority Weights This field sets the priority weights for Channel 0 during the round-robin arbitration between the DMA channels for the system bus. - 00: The priority weight is 1. - 01: The priority weight is 2. - 10: The priority weight is 3. - 11: The priority weight is 4. This field is present in all DWC_gmac configurations except GMAC-AXI when you select the AV feature. Otherwise, this field is reserved and read-only (RO). 28 2 read-write TXPR Transmit Priority When set, this bit indicates that the transmit DMA has higher priority than the receive DMA during arbitration for the system-side bus. In the GMAC-AXI configuration, this bit is reserved and read-only (RO). 27 1 read-write MB Mixed Burst When this bit is set high and the FB bit is low, the AHB master interface starts all bursts of length more than 16 with INCR (undefined burst), whereas it reverts to fixed burst transfers (INCRx and SINGLE) for burst length of 16 and less. 26 1 read-write AAL Address-Aligned Beats When this bit is set high and the FB bit is equal to 1, the AHB or AXI interface generates all bursts aligned to the start address LS bits. If the FB bit is equal to 0, the first burst (accessing the start address of data buffer) is not aligned, but subsequent bursts are aligned to the address. 25 1 read-write PBLX8 PBLx8 Mode When set high, this bit multiplies the programmed PBL value (Bits [22:17] and Bits[13:8]) eight times. Therefore, the DMA transfers the data in 8, 16, 32, 64, 128, and 256 beats depending on the PBL value. 24 1 read-write USP Use Separate PBL When set high, this bit configures the Rx DMA to use the value configured in Bits [22:17] as PBL. The PBL value in Bits [13:8] is applicable only to the Tx DMA operations. When reset to low, the PBL value in Bits [13:8] is applicable for both DMA engines. 23 1 read-write RPBL Rx DMA PBL This field indicates the maximum number of beats to be transferred in one Rx DMA transaction. This is the maximum value that is used in a single block Read or Write. The Rx DMA always attempts to burst as specified in the RPBL bit each time it starts a Burst transfer on the host bus. You can program RPBL with values of 1, 2, 4, 8, 16, and 32. Any other value results in undefined behavior. This field is valid and applicable only when USP is set high. 17 6 read-write FB Fixed Burst This bit controls whether the AHB or AXI master interface performs fixed burst transfers or not. When set, the AHB interface uses only SINGLE, INCR4, INCR8, or INCR16 during start of the normal burst transfers. When reset, the AHB or AXI interface uses SINGLE and INCR burst transfer operations. 16 1 read-write PR Priority Ratio These bits control the priority ratio in the weighted round-robin arbitration between the Rx DMA and Tx DMA. These bits are valid only when Bit 1 (DA) is reset. The priority ratio is Rx:Tx or Tx:Rx depending on whether Bit 27 (TXPR) is reset or set. - 00: The Priority Ratio is 1:1. - 01: The Priority Ratio is 2:1. - 10: The Priority Ratio is 3:1. - 11: The Priority Ratio is 4:1. 14 2 read-write PBL Programmable Burst Length These bits indicate the maximum number of beats to be transferred in one DMA transaction. This is the maximum value that is used in a single block Read or Write. The DMA always attempts to burst as specified in PBL each time it starts a Burst transfer on the host bus. PBL can be programmed with permissible values of 1, 2, 4, 8, 16, and 32. Any other value results in undefined behavior. When USP is set high, this PBL value is applicable only for Tx DMA transactions. If the number of beats to be transferred is more than 32, then perform the following steps: 1. Set the PBLx8 mode. 2. Set the PBL. 8 6 read-write ATDS Alternate Descriptor Size When set, the size of the alternate descriptor (described in “Alternate or Enhanced Descriptors” on page 545) increases to 32 bytes (8 DWORDS). This is required when the Advanced Timestamp feature or the IPC Full Checksum Offload Engine (Type 2) is enabled in the receiver. The enhanced descriptor is not required if the Advanced Timestamp and IPC Full Checksum Offload Engine (Type 2) features are not enabled. In such case, you can use the 16 bytes descriptor to save 4 bytes of memory. This bit is present only when you select the Alternate Descriptor feature and any one of the following features during core configuration: - Advanced Timestamp feature - IPC Full Checksum Offload Engine (Type 2) feature Otherwise, this bit is reserved and is read-only. When reset, the descriptor size reverts back to 4 DWORDs (16 bytes). 7 1 read-write DSL Descriptor Skip Length This bit specifies the number of Word, Dword, or Lword (depending on the 32-bit, 64-bit, or 128-bit bus) to skip between two unchained descriptors. The address skipping starts from the end of current descriptor to the start of next descriptor. When the DSL value is equal to zero, the descriptor table is taken as contiguous by the DMA in Ring mode. 2 5 read-write DA DMA Arbitration Scheme This bit specifies the arbitration scheme between the transmit and receive paths of Channel 0. - 0: Weighted round-robin with Rx:Tx or Tx:Rx The priority between the paths is according to the priority specified in Bits [15:14] (PR) and priority weights specified in Bit 27 (TXPR). - 1: Fixed priority The transmit path has priority over receive path when Bit 27 (TXPR) is set. Otherwise, receive path has priority over the transmit path. 1 1 read-write SWR Software Reset When this bit is set, the MAC DMA Controller resets the logic and all internal registers of the MAC. It is cleared automatically after the reset operation is complete in all of the DWC_gmac clock domains. Before reprogramming any register of the DWC_gmac, you should read a zero (0) value in this bit. Note: - The Software reset function is driven only by this bit. Bit 0 of Register 64 (Channel 1 Bus Mode Register) or Register 128 (Channel 2 Bus Mode Register) has no impact on the Software reset function. - The reset operation is completed only when all resets in all active clock domains are de-asserted. Therefore, it is essential that all PHY inputs clocks (applicable for the selected PHY interface) are present for the software reset completion. The time to complete the software reset operation depends on the frequency of the slowest active clock. 0 1 read-write DMA_TX_POLL_DEMAND Transmit Poll Demand Register 0x1004 32 0x00000000 0xFFFFFFFF TPD Transmit Poll Demand When these bits are written with any value, the DMA reads the current descriptor to which the Register 18 (Current Host Transmit Descriptor Register) is pointing. If that descriptor is not available (owned by the Host), the transmission returns to the Suspend state and Bit 2 (TU) of Register 5 (Status Register) is asserted. If the descriptor is available, the transmission resumes. 0 32 read-write DMA_RX_POLL_DEMAND Receive Poll Demand Register 0x1008 32 0x00000000 0xFFFFFFFF RPD Receive Poll Demand When these bits are written with any value, the DMA reads the current descriptor to which the Register 19 (Current Host Receive Descriptor Register) is pointing. If that descriptor is not available (owned by the Host), the reception returns to the Suspended state and Bit 7 (RU) of Register 5 (Status Register) is asserted. If the descriptor is available, the Rx DMA returns to the active state. 0 32 read-write DMA_RX_DESC_LIST_ADDR Receive Descriptor List Address Register 0x100c 32 0x00000000 0xFFFFFFFF RDESLA Start of Receive List This field contains the base address of the first descriptor in the Receive Descriptor list. The LSB bits (1:0, 2:0, or 3:0) for 32-bit, 64-bit, or 128-bit bus width are ignored and internally taken as all-zero by the DMA. Therefore, these LSB bits are read-only (RO). 0 32 read-write DMA_TX_DESC_LIST_ADDR Transmit Descriptor List Address Register 0x1010 32 0x00000000 0xFFFFFFFF TDESLA Start of Transmit List This field contains the base address of the first descriptor in the Transmit Descriptor list. The LSB bits (1:0, 2:0, 3:0) for 32-bit, 64-bit, or 128-bit bus width are ignored and are internally taken as all-zero by the DMA. Therefore, these LSB bits are read-only (RO). 0 32 read-write DMA_STATUS Status Register 0x1014 32 0x00000000 0x7FFFE7FF GLPII GLPII: GMAC LPI Interrupt (for Channel 0) This bit indicates an interrupt event in the LPI logic of the MAC. To reset this bit to 1'b0, the software must read the corresponding registers in the DWC_gmac to get the exact cause of the interrupt and clear its source. Note: GLPII status is given only in Channel 0 DMA register and is applicable only when the Energy Efficient Ethernet feature is enabled. Otherwise, this bit is reserved. When this bit is high, the interrupt signal from the MAC (sbd_intr_o) is high. -or- GTMSI: GMAC TMS Interrupt (for Channel 1 and Channel 2) This bit indicates an interrupt event in the traffic manager and scheduler logic of DWC_gmac. To reset this bit, the software must read the corresponding registers (Channel Status Register) to get the exact cause of the interrupt and clear its source. Note: GTMSI status is given only in Channel 1 and Channel 2 DMA register when the AV feature is enabled and corresponding additional transmit channels are present. Otherwise, this bit is reserved. When this bit is high, the interrupt signal from the MAC (sbd_intr_o) is high. 30 1 read-write TTI Timestamp Trigger Interrupt This bit indicates an interrupt event in the Timestamp Generator block of the DWC_gmac. The software must read the corresponding registers in the DWC_gmac to get the exact cause of the interrupt and clear its source to reset this bit to 1'b0. When this bit is high, the interrupt signal from the DWC_gmac subsystem (sbd_intr_o) is high. This bit is applicable only when the IEEE 1588 Timestamp feature is enabled. Otherwise, this bit is reserved. 29 1 read-write GPI GMAC PMT Interrupt This bit indicates an interrupt event in the PMT module of the DWC_gmac. The software must read the PMT Control and Status Register in the MAC to get the exact cause of interrupt and clear its source to reset this bit to 1’b0. The interrupt signal from the DWC_gmac subsystem (sbd_intr_o) is high when this bit is high. This bit is applicable only when the Power Management feature is enabled. Otherwise, this bit is reserved. Note: The GPI and pmt_intr_o interrupts are generated in different clock domains. 28 1 read-write GMI GMAC MMC Interrupt This bit reflects an interrupt event in the MMC module of the DWC_gmac. The software must read the corresponding registers in the DWC_gmac to get the exact cause of the interrupt and clear the source of interrupt to make this bit as 1’b0. The interrupt signal from the DWC_gmac subsystem (sbd_intr_o) is high when this bit is high. This bit is applicable only when the MAC Management Counters (MMC) are enabled. Otherwise, this bit is reserved. 27 1 read-write GLI GMAC Line Interface Interrupt When set, this bit reflects any of the following interrupt events in the DWC_gmac interfaces (if present and enabled in your configuration): - PCS (TBI, RTBI, or SGMII): Link change or auto-negotiation complete event - SMII or RGMII: Link change event - General Purpose Input Status (GPIS): Any LL or LH event on the gpi_i input ports To identify the exact cause of the interrupt, the software must first read Bit 11 and Bits[2:0] of Register 14 (Interrupt Status Register) and then to clear the source of interrupt (which also clears the GLI interrupt), read any of the following corresponding registers: - PCS (TBI, RTBI, or SGMII): Register 49 (AN Status Register) - SMII or RGMII: Register 54 (SGMII/RGMII/SMII Control and Status Register) - General Purpose Input (GPI): Register 56 (General Purpose IO Register) The interrupt signal from the DWC_gmac subsystem (sbd_intr_o) is high when this bit is high. 26 1 read-write EB Error Bits This field indicates the type of error that caused a Bus Error, for example, error response on the AHB or AXI interface. This field is valid only when Bit 13 (FBI) is set. This field does not generate an interrupt. - 0 0 0: Error during Rx DMA Write Data Transfer - 0 1 1: Error during Tx DMA Read Data Transfer - 1 0 0: Error during Rx DMA Descriptor Write Access - 1 0 1: Error during Tx DMA Descriptor Write Access - 1 1 0: Error during Rx DMA Descriptor Read Access - 1 1 1: Error during Tx DMA Descriptor Read Access Note: 001 and 010 are reserved. 23 3 read-write TS Transmit Process State This field indicates the Transmit DMA FSM state. This field does not generate an interrupt. - 3’b000: Stopped; Reset or Stop Transmit Command issued - 3’b001: Running; Fetching Transmit Transfer Descriptor - 3’b010: Running; Waiting for status - 3’b011: Running; Reading Data from host memory buffer and queuing it to transmit buffer (Tx FIFO) - 3’b100: TIME_STAMP write state - 3’b101: Reserved for future use - 3’b110: Suspended; Transmit Descriptor Unavailable or Transmit Buffer Underflow - 3’b111: Running; Closing Transmit Descriptor 20 3 read-write RS Receive Process State This field indicates the Receive DMA FSM state. This field does not generate an interrupt. - 3’b000: Stopped: Reset or Stop Receive Command issued - 3’b001: Running: Fetching Receive Transfer Descriptor - 3’b010: Reserved for future use - 3’b011: Running: Waiting for receive packet - 3’b100: Suspended: Receive Descriptor Unavailable - 3’b101: Running: Closing Receive Descriptor - 3’b110: TIME_STAMP write state - 3’b111: Running: Transferring the receive packet data from receive buffer to host memory 17 3 read-write NIS Normal Interrupt Summary Normal Interrupt Summary bit value is the logical OR of the following bits when the corresponding interrupt bits are enabled in Register 7 (Interrupt Enable Register): - Register 5[0]: Transmit Interrupt - Register 5[2]: Transmit Buffer Unavailable - Register 5[6]: Receive Interrupt - Register 5[14]: Early Receive Interrupt Only unmasked bits (interrupts for which interrupt enable is set in Register 7) affect the Normal Interrupt Summary bit. This is a sticky bit and must be cleared (by writing 1 to this bit) each time a corresponding bit, which causes NIS to be set, is cleared. 16 1 read-write AIS Abnormal Interrupt Summary Abnormal Interrupt Summary bit value is the logical OR of the following when the corresponding interrupt bits are enabled in Register 7 (Interrupt Enable Register): - Register 5[1]: Transmit Process Stopped - Register 5[3]: Transmit Jabber Timeout - Register 5[4]: Receive FIFO Overflow - Register 5[5]: Transmit Underflow - Register 5[7]: Receive Buffer Unavailable - Register 5[8]: Receive Process Stopped - Register 5[9]: Receive Watchdog Timeout - Register 5[10]: Early Transmit Interrupt - Register 5[13]: Fatal Bus Error Only unmasked bits affect the Abnormal Interrupt Summary bit. This is a sticky bit and must be cleared (by writing 1 to this bit) each time a corresponding bit, which causes AIS to be set, is cleared. 15 1 read-write ERI Early Receive Interrupt This bit indicates that the DMA filled the first data buffer of the packet. This bit is cleared when the software writes 1 to this bit or Bit 6 (RI) of this register is set (whichever occurs earlier). 14 1 read-write FBI Fatal Bus Error Interrupt This bit indicates that a bus error occurred, as described in Bits [25:23]. When this bit is set, the corresponding DMA engine disables all of its bus accesses. 13 1 read-write ETI Early Transmit Interrupt This bit indicates that the frame to be transmitted is fully transferred to the MTL Transmit FIFO. 10 1 read-write RWT Receive Watchdog Timeout When set, this bit indicates that the Receive Watchdog Timer expired while receiving the current frame and the current frame is truncated after the watchdog timeout. 9 1 read-write RPS Receive Process Stopped This bit is asserted when the Receive Process enters the Stopped state. 8 1 read-write RU Receive Buffer Unavailable This bit indicates that the host owns the Next Descriptor in the Receive List and the DMA cannot acquire it. The Receive Process is suspended. To resume processing Receive descriptors, the host should change the ownership of the descriptor and issue a Receive Poll Demand command. If no Receive Poll Demand is issued, the Receive Process resumes when the next recognized incoming frame is received. This bit is set only when the previous Receive Descriptor is owned by the DMA. 7 1 read-write RI Receive Interrupt This bit indicates that the frame reception is complete. When reception is complete, the Bit 31 of RDES1 (Disable Interrupt on Completion) is reset in the last Descriptor, and the specific frame status information is updated in the descriptor. The reception remains in the Running state. 6 1 read-write UNF Transmit Underflow This bit indicates that the Transmit Buffer had an Underflow during frame transmission. Transmission is suspended and an Underflow Error TDES0[1] is set. 5 1 read-write OVF Receive Overflow This bit indicates that the Receive Buffer had an Overflow during frame reception. If the partial frame is transferred to the application, the overflow status is set in RDES0[11]. 4 1 read-write TJT Transmit Jabber Timeout This bit indicates that the Transmit Jabber Timer expired, which happens when the frame size exceeds 2,048 (10,240 bytes when the Jumbo frame is enabled). When the Jabber Timeout occurs, the transmission process is aborted and placed in the Stopped state. This causes the Transmit Jabber Timeout TDES0[14] flag to assert. 3 1 read-write TU Transmit Buffer Unavailable This bit indicates that the host owns the Next Descriptor in the Transmit List and the DMA cannot acquire it. Transmission is suspended. Bits[22:20] explain the Transmit Process state transitions. To resume processing Transmit descriptors, the host should change the ownership of the descriptor by setting TDES0[31] and then issue a Transmit Poll Demand command. 2 1 read-write TPS Transmit Process Stopped This bit is set when the transmission is stopped. 1 1 read-write TI Transmit Interrupt This bit indicates that the frame transmission is complete. When transmission is complete, Bit 31 (OWN) of TDES0 is reset, and the specific frame status information is updated in the descriptor. 0 1 read-write DMA_OP_MODE Operation Mode Register 0x1018 32 0x00000000 0x13F1FFFE DT Disable Dropping of TCP/IP Checksum Error Frames When this bit is set, the MAC does not drop the frames which only have errors detected by the Receive Checksum Offload engine. Such frames do not have any errors (including FCS error) in the Ethernet frame received by the MAC but have errors only in the encapsulated payload. When this bit is reset, all error frames are dropped if the FEF bit is reset. If the IPC Full Checksum Offload Engine (Type 2) is disabled, this bit is reserved (RO with value 1'b0). 28 1 read-write RSF Receive Store and Forward When this bit is set, the MTL reads a frame from the Rx FIFO only after the complete frame has been written to it, ignoring the RTC bits. When this bit is reset, the Rx FIFO operates in the cut-through mode, subject to the threshold specified by the RTC bits. 25 1 read-write DFF Disable Flushing of Received Frames When this bit is set, the Rx DMA does not flush any frames because of the unavailability of receive descriptors or buffers as it does normally when this bit is reset. (See “Receive Process Suspended” on page 83.) 24 1 read-write RFA_2 MSB of Threshold for Activating Flow Control If the DWC_gmac is configured for an Rx FIFO size of 8 KB or more, this bit (when set) provides additional threshold levels for activating the flow control in both half-duplex and full-duplex modes. This bit (as Most Significant Bit), along with the RFA (Bits [10:9]), gives the following thresholds for activating flow control: - 100: Full minus 5 KB, that is, FULL — 5 KB - 101: Full minus 6 KB, that is, FULL — 6 KB - 110: Full minus 7 KB, that is, FULL — 7 KB - 111: Reserved This bit is reserved (and RO) if the Rx FIFO is 4 KB or less deep. 23 1 read-write RFD_2 MSB of Threshold for Deactivating Flow Control If the DWC_gmac is configured for Rx FIFO size of 8 KB or more, this bit (when set) provides additional threshold levels for deactivating the flow control in both half-duplex and full-duplex modes. This bit (as Most Significant Bit) along with the RFD (Bits [12:11]) gives the following thresholds for deactivating flow control: - 100: Full minus 5 KB, that is, FULL — 5 KB - 101: Full minus 6 KB, that is, FULL — 6 KB - 110: Full minus 7 KB, that is, FULL — 7 KB - 111: Reserved This bit is reserved (and RO) if the Rx FIFO is 4 KB or less deep. 22 1 read-write TSF Transmit Store and Forward When this bit is set, transmission starts when a full frame resides in the MTL Transmit FIFO. When this bit is set, the TTC values specified in Bits [16:14] are ignored. This bit should be changed only when the transmission is stopped. 21 1 read-write FTF Flush Transmit FIFO When this bit is set, the transmit FIFO controller logic is reset to its default values and thus all data in the Tx FIFO is lost or flushed. This bit is cleared internally when the flushing operation is complete. The Operation Mode register should not be written to until this bit is cleared. The data which is already accepted by the MAC transmitter is not flushed. It is scheduled for transmission and results in underflow and runt frame transmission. 20 1 read-write TTC Transmit Threshold Control These bits control the threshold level of the MTL Transmit FIFO. Transmission starts when the frame size within the MTL Transmit FIFO is larger than the threshold. In addition, full frames with a length less than the threshold are also transmitted. These bits are used only when Bit 21 (TSF) is reset. - 000: 64 - 001: 128 - 010: 192 - 011: 256 - 100: 40 - 101: 32 - 110: 24 - 111: 16 14 3 read-write ST Start or Stop Transmission Command When this bit is set, transmission is placed in the Running state, and the DMA checks the Transmit List at the current position for a frame to be transmitted. Descriptor acquisition is attempted either from the current position in the list, which is the Transmit List Base Address set by Register 4 (Transmit Descriptor List Address Register), or from the position retained when transmission was stopped previously. If the DMA does not own the current descriptor, transmission enters the Suspended state and Bit 2 (Transmit Buffer Unavailable) of Register 5 (Status Register) is set. The Start Transmission command is effective only when transmission is stopped. If the command is issued before setting Register 4 (Transmit Descriptor List Address Register), then the DMA behavior is unpredictable. When this bit is reset, the transmission process is placed in the Stopped state after completing the transmission of the current frame. The Next Descriptor position in the Transmit List is saved, and it becomes the current position when transmission is restarted. To change the list address, you need to program Register 4 (Transmit Descriptor List Address Register) with a new value when this bit is reset. The new value is considered when this bit is set again. The stop transmission command is effective only when the transmission of the current frame is complete or the transmission is in the Suspended state. 13 1 read-write RFD Threshold for Deactivating Flow Control (in half-duplex and full-duplex modes) These bits control the threshold (Fill-level of Rx FIFO) at which the flow control is de-asserted after activation. - 00: Full minus 1 KB, that is, FULL — 1 KB - 01: Full minus 2 KB, that is, FULL — 2 KB - 10: Full minus 3 KB, that is, FULL — 3 KB - 11: Full minus 4 KB, that is, FULL — 4 KB The de-assertion is effective only after flow control is asserted. If the Rx FIFO is 8 KB or more, an additional Bit (RFD_2) is used for more threshold levels as described in Bit 22. These bits are reserved and read-only when the Rx FIFO depth is less than 4 KB. 11 2 read-write RFA Threshold for Activating Flow Control (in half-duplex and full-duplex modes) These bits control the threshold (Fill level of Rx FIFO) at which the flow control is activated. - 00: Full minus 1 KB, that is, FULL—1KB. - 01: Full minus 2 KB, that is, FULL—2KB. - 10: Full minus 3 KB, that is, FULL—3KB. - 11: Full minus 4 KB, that is, FULL—4KB. These values are applicable only to Rx FIFOs of 4 KB or more and when Bit 8 (EFC) is set high. If the Rx FIFO is 8 KB or more, an additional Bit (RFA_2) is used for more threshold levels as described in Bit 23. These bits are reserved and read-only when the depth of Rx FIFO is less than 4 KB. Note: When FIFO size is exactly 4 KB, although the DWC_gmac allows you to program the value of these bits to 11, the software should not program these bits to 2'b11. The value 2'b11 means flow control on FIFO empty condition 9 2 read-write EFC Enable HW Flow Control When this bit is set, the flow control signal operation based on the fill-level of Rx FIFO is enabled. When reset, the flow control operation is disabled. This bit is not used (reserved and always reset) when the Rx FIFO is less than 4 KB. 8 1 read-write FEF Forward Error Frames When this bit is reset, the Rx FIFO drops frames with error status (CRC error, collision error, GMII_ER, giant frame, watchdog timeout, or overflow). However, if the start byte (write) pointer of a frame is already transferred to the read controller side (in Threshold mode), then the frame is not dropped. In the GMAC-MTL configuration in which the Frame Length FIFO is also enabled during core configuration, the Rx FIFO drops the error frames if that frame's start byte is not transferred (output) on the ARI bus. When the FEF bit is set, all frames except runt error frames are forwarded to the DMA. If the Bit 25 (RSF) is set and the Rx FIFO overflows when a partial frame is written, then the frame is dropped irrespective of the FEF bit setting. However, if the Bit 25 (RSF) is reset and the Rx FIFO overflows when a partial frame is written, then a partial frame may be forwarded to the DMA. Note: When FEF bit is reset, the giant frames are dropped if the giant frame status is given in Rx Status (in Table 8-6 or Table 8-23) in the following configurations: - The IP checksum engine (Type 1) and full checksum offload engine (Type 2) are not selected. - The advanced timestamp feature is not selected but the extended status is selected. The extended status is available with the following features: - L3-L4 filter in GMAC-CORE or GMAC-MTL configurations - Full checksum offload engine (Type 2) with enhanced descriptor format in the GMAC-DMA, GMAC-AHB, or GMAC-AXI configurations. 7 1 read-write FUF Forward Undersized Good Frames When set, the Rx FIFO forwards Undersized frames (that is, frames with no Error and length less than 64 bytes) including pad-bytes and CRC. When reset, the Rx FIFO drops all frames of less than 64 bytes, unless a frame is already transferred because of the lower value of Receive Threshold, for example, RTC = 01. 6 1 read-write DGF Drop Giant Frames When set, the MAC drops the received giant frames in the Rx FIFO, that is, frames that are larger than the computed giant frame limit. When reset, the MAC does not drop the giant frames in the Rx FIFO. Note: This bit is available in the following configurations in which the giant frame status is not provided in Rx status and giant frames are not dropped by default: - Configurations in which IP Checksum Offload (Type 1) is selected in Rx - Configurations in which the IPC Full Checksum Offload Engine (Type 2) is selected in Rx with normal descriptor format - Configurations in which the Advanced Timestamp feature is selected In all other configurations, this bit is not used (reserved and always reset). 5 1 read-write RTC Receive Threshold Control These two bits control the threshold level of the MTL Receive FIFO. Transfer (request) to DMA starts when the frame size within the MTL Receive FIFO is larger than the threshold. In addition, full frames with length less than the threshold are automatically transferred. The value of 11 is not applicable if the configured Receive FIFO size is 128 bytes. These bits are valid only when the RSF bit is zero, and are ignored when the RSF bit is set to 1. - 00: 64 - 01: 32 - 10: 96 - 11: 128 3 2 read-write OSF Operate on Second Frame When this bit is set, it instructs the DMA to process the second frame of the Transmit data even before the status for the first frame is obtained. 2 1 read-write SR Start or Stop Receive When this bit is set, the Receive process is placed in the Running state. The DMA attempts to acquire the descriptor from the Receive list and processes the incoming frames. The descriptor acquisition is attempted from the current position in the list, which is the address set by the Register 3 (Receive Descriptor List Address Register) or the position retained when the Receive process was previously stopped. If the DMA does not own the descriptor, reception is suspended and Bit 7 (Receive Buffer Unavailable) of Register 5 (Status Register) is set. The Start Receive command is effective only when the reception has stopped. If the command is issued before setting Register 3 (Receive Descriptor List Address Register), the DMA behavior is unpredictable. When this bit is cleared, the Rx DMA operation is stopped after the transfer of the current frame. The next descriptor position in the Receive list is saved and becomes the current position after the Receive process is restarted. The Stop Receive command is effective only when the Receive process is in either the Running (waiting for receive packet) or in the Suspended state. 1 1 read-write DMA_INTR_EN Interrupt Enable Register 0x101c 32 0x00000000 0x0001E7FF NIE Normal Interrupt Summary Enable When this bit is set, normal interrupt summary is enabled.

In such a scenario, the Missed frame counter is reset to all-zeros and this bit indicates that the rollover happened. 16 1 read-write MISFRMCNT Missed Frame Counter This field indicates the number of frames missed by the controller because of the Host Receive Buffer being unavailable. This counter is incremented each time the DMA discards an incoming frame. The counter is cleared when this register is read with mci_be_i[0] at 1’b1. 0 16 read-write DMA_RX_INTR_WDOG Receive Interrupt Watchdog Timer Register 0x1024 32 0x00000000 0x000000FF RIWT RI Watchdog Timer Count This bit indicates the number of system clock cycles multiplied by 256 for which the watchdog timer is set. The watchdog timer gets triggered with the programmed value after the Rx DMA completes the transfer of a frame for which the RI status bit is not set because of the setting in the corresponding descriptor RDES1[31]. When the watchdog timer runs out, the RI bit is set and the timer is stopped. The watchdog timer is reset when the RI bit is set high because of automatic setting of RI as per RDES1[31] of any received frame. 0 8 read-write DMA_AXI_MODE AXI Bus Mode Register 0x1028 32 0x00000000 0xC0FF30FF EN_LPI Enable Low Power Interface (LPI) When set to 1, this bit enables the LPI mode supported by the GMAC-AXI configuration and accepts the LPI request from the AXI System Clock controller.

[host mode only] This field is Read/Write only if Programmable Frame List Flag in the HCCPARAMS registers is set to one. This field specifies the size of the frame list that controls which bits in the Frame Index Register should be used for the Frame List Current index. NOTE: This field is made up from USBCMD bits 15, 3 and 2. Value Meaning 0b000 - 1024 elements (4096 bytes) Default value 0b001 - 512 elements (2048 bytes) 0b010 - 256 elements (1024 bytes) 0b011 - 128 elements (512 bytes) 0b100 - 64 elements (256 bytes) 0b101 - 32 elements (128 bytes) 0b110 - 16 elements (64 bytes) 0b111 - 8 elements (32 bytes) 15 1 read-write ATDTW ATDTW Add dTD TripWire - Read/Write. [device mode only] This bit is used as a semaphore to ensure proper addition of a new dTD to an active (primed) endpoint's linked list. This bit is set and cleared by software. This bit would also be cleared by hardware when state machine is hazard region for which adding a dTD to a primed endpoint may go unrecognized. 14 1 read-write SUTW SUTW Setup TripWire - Read/Write. [device mode only] This bit is used as a semaphore to ensure that the setup data payload of 8 bytes is extracted from a QH by the DCD without being corrupted. If the setup lockout mode is off (SLOM bit in USB core register n_USBMODE, see USBMODE ) then there is a hazard when new setup data arrives while the DCD is copying the setup data payload from the QH for a previous setup packet. This bit is set and cleared by software. This bit would also be cleared by hardware when a hazard detected. 13 1 read-write PRM Asynchronous Schedule start- Write only， host mode only。 this bit is used to notify hostcontroller to start async schedule immediately. 12 1 write-only ASPE ASPE Asynchronous Schedule Park Mode Enable - Read/Write. If the Asynchronous Park Capability bit in the HCCPARAMS register is a one, then this bit defaults to a 1h and is R/W. Otherwise the bit must be a zero and is RO. Software uses this bit to enable or disable Park mode. When this bit is one, Park mode is enabled. When this bit is a zero, Park mode is disabled. NOTE: ASPE bit reset value: '0b' for OTG controller . 11 1 read-write ASP ASP Asynchronous Schedule Park Mode Count - Read/Write. If the Asynchronous Park Capability bit in the HCCPARAMS register is a one, then this field defaults to 3h and is R/W. Otherwise it defaults to zero and is Read-Only. It contains a count of the number of successive transactions the host controller is allowed to execute from a high-speed queue head on the Asynchronous schedule before continuing traversal of the Asynchronous schedule. Valid values are 1h to 3h. Software must not write a zero to this bit when Park Mode Enable is a one as this will result in undefined behavior. This field is set to 3h in all controller core. 8 2 read-write IAA IAA Interrupt on Async Advance Doorbell - Read/Write. This bit is used as a doorbell by software to tell the host controller to issue an interrupt the next time it advances asynchronous schedule. Software must write a 1 to this bit to ring the doorbell. When the host controller has evicted all appropriate cached schedule states, it sets the Interrupt on Async Advance status bit in the USBSTS register. If the Interrupt on Sync Advance Enable bit in the USBINTR register is one, then the host controller will assert an interrupt at the next interrupt threshold. The host controller sets this bit to zero after it has set the Interrupt on Sync Advance status bit in the USBSTS register to one. Software should not write a one to this bit when the asynchronous schedule is inactive. Doing so will yield undefined results. This bit is only used in host mode. Writing a one to this bit when device mode is selected will have undefined results. 6 1 read-write ASE ASE Asynchronous Schedule Enable - Read/Write. Default 0b. This bit controls whether the host controller skips processing the Asynchronous Schedule. Only the host controller uses this bit. Values Meaning 0 - Do not process the Asynchronous Schedule. 1 - Use the ASYNCLISTADDR register to access the Asynchronous Schedule. 5 1 read-write PSE PSE Periodic Schedule Enable- Read/Write. Default 0b. This bit controls whether the host controller skips processing the Periodic Schedule. Only the host controller uses this bit. Values Meaning 0 - Do not process the Periodic Schedule 1 - Use the PERIODICLISTBASE register to access the Periodic Schedule. 4 1 read-write FS_1 FS_1 See description at bit 15 2 2 read-write RST RST Controller Reset (RESET) - Read/Write. Software uses this bit to reset the controller. This bit is set to zero by the Host/Device Controller when the reset process is complete. Software cannot terminate the reset process early by writing a zero to this register. Host operation mode: When software writes a one to this bit, the Controller resets its internal pipelines, timers, counters, state machines etc. to their initial value. Any transaction currently in progress on USB is immediately terminated. A USB reset is not driven on downstream ports. Software should not set this bit to a one when the HCHalted bit in the USBSTS register is a zero. Attempting to reset an actively running host controller will result in undefined behavior. Device operation mode: When software writes a one to this bit, the Controller resets its internal pipelines, timers, counters, state machines etc. to their initial value. Writing a one to this bit when the device is in the attached state is not recommended, because the effect on an attached host is undefined. In order to ensure that the device is not in an attached state before initiating a device controller reset, all primed endpoints should be flushed and the USBCMD Run/Stop bit should be set to 0. 1 1 read-write RS RS Run/Stop (RS) - Read/Write. Default 0b. 1=Run. 0=Stop. Host operation mode: When set to '1b', the Controller proceeds with the execution of the schedule. The Controller continues execution as long as this bit is set to a one. When this bit is set to 0, the Host Controller completes the current transaction on the USB and then halts. The HC Halted bit in the status register indicates when the Controller has finished the transaction and has entered the stopped state. Software should not write a one to this field unless the controller is in the Halted state (that is, HCHalted in the USBSTS register is a one). Device operation mode: Writing a one to this bit will cause the controller to enable a pull-up on D+ and initiate an attach event. This control bit is not directly connected to the pull-up enable, as the pull-up will become disabled upon transitioning into high-speed mode. Software should use this bit to prevent an attach event before the controller has been properly initialized. Writing a 0 to this will cause a detach event. 0 1 read-write USBSTS USB Status Register 0x144 32 0x00000000 0x030DF1FF TI1 TI1 General Purpose Timer Interrupt 1(GPTINT1)--R/WC.

This bit is set when the counter in the GPTIMER0CTRL register transitions to zero, writing a one to this bit clears it. 24 1 read-write UPI USB Host Periodic Interrupt – RWC. Default = 0b. This bit is set by the Host Controller when the cause of an interrupt is a completion of a USB transaction where the Transfer Descriptor (TD) has an interrupt on complete (IOC) bit set and the TD was from the periodic schedule. This bit is also set by the Host Controller when a short packet is detected and the packet is on the periodic schedule. A short packet is when the actual number of bytes received was less than expected. This bit is not used by the device controller and will always be zero. 19 1 read-write UAI USB Host Asynchronous Interrupt – RWC. Default = 0b. This bit is set by the Host Controller when the cause of an interrupt is a completion of a USB transaction where the Transfer Descriptor (TD) has an interrupt on complete (IOC) bit set AND the TD was from the asynchronous schedule. This bit is also set by the Host when a short packet is detected and the packet is on the asynchronous schedule. A short packet is when the actual number of bytes received was less than expected. This bit is not used by the device controller and will always be zero 18 1 read-write NAKI NAKI NAK Interrupt Bit--RO. This bit is set by hardware when for a particular endpoint both the TX/RX Endpoint NAK bit and corresponding TX/RX Endpoint NAK Enable bit are set. This bit is automatically cleared by hardware when all Enabled TX/RX Endpoint NAK bits are cleared. 16 1 read-only AS AS Asynchronous Schedule Status - Read Only. This bit reports the current real status of the Asynchronous Schedule. When set to zero the asynchronous schedule status is disabled and if set to one the status is enabled. The Host Controller is not required to immediately disable or enable the Asynchronous Schedule when software transitions the Asynchronous Schedule Enable bit in the USBCMD register. When this bit and the Asynchronous Schedule Enable bit are the same value, the Asynchronous Schedule is either enabled (1) or disabled (0). Only used in the host operation mode. 15 1 read-only PS PS Periodic Schedule Status - Read Only. This bit reports the current real status of the Periodic Schedule. When set to zero the periodic schedule is disabled, and if set to one the status is enabled. The Host Controller is not required to immediately disable or enable the Periodic Schedule when software transitions the Periodic Schedule Enable bit in the USBCMD register. When this bit and the Periodic Schedule Enable bit are the same value, the Periodic Schedule is either enabled (1) or disabled (0). Only used in the host operation mode. 14 1 read-only RCL RCL Reclamation - Read Only. This is a read-only status bit used to detect an empty asynchronous schedule. Only used in the host operation mode. 13 1 read-only HCH HCH HCHaIted - Read Only. This bit is a zero whenever the Run/Stop bit is a one. The Controller sets this bit to one after it has stopped executing because of the Run/Stop bit being set to 0, either by software or by the Controller hardware (for example, an internal error). Only used in the host operation mode. Default value is '0b' for OTG core . This is because OTG core is not operating as host in default. Please see CM bit in USB_n_USBMODE register. NOTE: HCH bit reset value: '0b' for OTG controller core . 12 1 read-only SLI SLI DCSuspend - R/WC. When a controller enters a suspend state from an active state, this bit will be set to a one. The device controller clears the bit upon exiting from a suspend state. Only used in device operation mode. 8 1 read-write SRI SRI SOF Received - R/WC. When the device controller detects a Start Of (micro) Frame, this bit will be set to a one. When a SOF is extremely late, the device controller will automatically set this bit to indicate that an SOF was expected. Therefore, this bit will be set roughly every 1ms in device FS mode and every 125ms in HS mode and will be synchronized to the actual SOF that is received. Because the device controller is initialized to FS before connect, this bit will be set at an interval of 1ms during the prelude to connect and chirp. In host mode, this bit will be set every 125us and can be used by host controller driver as a time base. Software writes a 1 to this bit to clear it. 7 1 read-write URI URI USB Reset Received - R/WC. When the device controller detects a USB Reset and enters the default state, this bit will be set to a one. Software can write a 1 to this bit to clear the USB Reset Received status bit. Only used in device operation mode. 6 1 read-write AAI AAI Interrupt on Async Advance - R/WC. System software can force the host controller to issue an interrupt the next time the host controller advances the asynchronous schedule by writing a one to the Interrupt on Async Advance Doorbell bit in the n_USBCMD register. This status bit indicates the assertion of that interrupt source. Only used in host operation mode. 5 1 read-write SEI System Error – RWC. Default = 0b. In the BVCI implementation of the USBHS core, this bit is not used, and will always be cleared to '0b'. In the AMBA implementation, this bit will be set to '1b' when an Error response is seen by the master interface (HRESP[1:0]=ERROR) 4 1 read-write FRI FRI Frame List Rollover - R/WC. The Host Controller sets this bit to a one when the Frame List Index rolls over from its maximum value to zero. The exact value at which the rollover occurs depends on the frame list size. For example. If the frame list size (as programmed in the Frame List Size field of the USB_n_USBCMD register) is 1024, the Frame Index Register rolls over every time FRINDEX [13] toggles. Similarly, if the size is 512, the Host Controller sets this bit to a one every time FHINDEX [12] toggles. Only used in host operation mode. 3 1 read-write PCI PCI Port Change Detect - R/WC. The Host Controller sets this bit to a one when on any port a Connect Status occurs, a Port Enable/Disable Change occurs, or the Force Port Resume bit is set as the result of a J-K transition on the suspended port. The Device Controller sets this bit to a one when the port controller enters the full or high-speed operational state. When the port controller exits the full or high-speed operation states due to Reset or Suspend events, the notification mechanisms are the USB Reset Received bit and the DCSuspend bits Respectively. 2 1 read-write UEI UEI USB Error Interrupt (USBERRINT) - R/WC. When completion of a USB transaction results in an error condition, this bit is set by the Host/Device Controller. This bit is set along with the USBINT bit, if the TD on which the error interrupt occurred also had its interrupt on complete (IOC) bit set. 1 1 read-write UI UI USB Interrupt (USBINT) - R/WC. This bit is set by the Host/Device Controller when the cause of an interrupt is a completion of a USB transaction where the Transfer Descriptor (TD) has an interrupt on complete (IOC) bit set. This bit is also set by the Host/Device Controller when a short packet is detected. A short packet is when the actual number of bytes received was less than the expected number of bytes. 0 1 read-write USBINTR Interrupt Enable Register 0x148 32 0x00000000 0x030D01FF TIE1 TIE1 General Purpose Timer #1 Interrupt Enable When this bit is one and the TI1 bit in n_USBSTS register is a one the controller will issue an interrupt. 25 1 read-write TIE0 TIE0 General Purpose Timer #0 Interrupt Enable When this bit is one and the TI0 bit in n_USBSTS register is a one the controller will issue an interrupt. 24 1 read-write UPIE UPIE USB Host Periodic Interrupt Enable When this bit is one, and the UPI bit in the n_USBSTS register is one, host controller will issue an interrupt at the next interrupt threshold. 19 1 read-write UAIE UAIE USB Host Asynchronous Interrupt Enable When this bit is one, and the UAI bit in the n_USBSTS register is one, host controller will issue an interrupt at the next interrupt threshold. 18 1 read-write NAKE NAKE NAK Interrupt Enable When this bit is one and the NAKI bit in n_USBSTS register is a one the controller will issue an interrupt. 16 1 read-only SLE SLE Sleep Interrupt Enable When this bit is one and the SLI bit in n_n_USBSTS register is a one the controller will issue an interrupt. Only used in device operation mode. 8 1 read-write SRE SRE SOF Received Interrupt Enable When this bit is one and the SRI bit in n_USBSTS register is a one the controller will issue an interrupt. 7 1 read-write URE URE USB Reset Interrupt Enable When this bit is one and the URI bit in n_USBSTS register is a one the controller will issue an interrupt. Only used in device operation mode. 6 1 read-write AAE AAE Async Advance Interrupt Enable When this bit is one and the AAI bit in n_USBSTS register is a one the controller will issue an interrupt. Only used in host operation mode. 5 1 read-write SEE SEE System Error Interrupt Enable When this bit is one and the SEI bit in n_USBSTS register is a one the controller will issue an interrupt. Only used in host operation mode. 4 1 read-write FRE FRE Frame List Rollover Interrupt Enable When this bit is one and the FRI bit in n_USBSTS register is a one the controller will issue an interrupt. Only used in host operation mode. 3 1 read-write PCE PCE Port Change Detect Interrupt Enable When this bit is one and the PCI bit in n_USBSTS register is a one the controller will issue an interrupt. 2 1 read-write UEE UEE USB Error Interrupt Enable When this bit is one and the UEI bit in n_USBSTS register is a one the controller will issue an interrupt. 1 1 read-write UE UE USB Interrupt Enable When this bit is one and the UI bit in n_USBSTS register is a one the controller will issue an interrupt. 0 1 read-write FRINDEX USB Frame Index Register 0x14c 32 0x00000000 0x00003FFF FRINDEX FRINDEX Frame Index. The value, in this register, increments at the end of each time frame (micro-frame). Bits [N: 3] are used for the Frame List current index. This means that each location of the frame list is accessed 8 times (frames or micro-frames) before moving to the next index. The following illustrates values of N based on the value of the Frame List Size field in the USBCMD register, when used in host mode. USBCMD [Frame List Size] Number Elements N In device mode the value is the current frame number of the last frame transmitted. It is not used as an index. In either mode bits 2:0 indicate the current microframe. The bit field values description below is represented as (Frame List Size) Number Elements N. 00000000000000 - (1024) 12 00000000000001 - (512) 11 00000000000010 - (256) 10 00000000000011 - (128) 9 00000000000100 - (64) 8 00000000000101 - (32) 7 00000000000110 - (16) 6 00000000000111 - (8) 5 0 14 read-write DEVICEADDR Device Address Register UNION_154 0x154 32 0x00000000 0xFF000000 USBADR USBADR Device Address. These bits correspond to the USB device address 25 7 read-write USBADRA USBADRA Device Address Advance. Default=0. When this bit is '0', any writes to USBADR are instantaneous. When this bit is written to a '1' at the same time or before USBADR is written, the write to the USBADR field is staged and held in a hidden register. After an IN occurs on endpoint 0 and is ACKed, USBADR will be loaded from the holding register. Hardware will automatically clear this bit on the following conditions: 1) IN is ACKed to endpoint 0. (USBADR is updated from staging register). 2) OUT/SETUP occur to endpoint 0. (USBADR is not updated). 3) Device Reset occurs (USBADR is reset to 0). NOTE: After the status phase of the SET_ADDRESS descriptor, the DCD has 2 ms to program the USBADR field. This mechanism will ensure this specification is met when the DCD can not write of the device address within 2ms from the SET_ADDRESS status phase. If the DCD writes the USBADR with USBADRA=1 after the SET_ADDRESS data phase (before the prime of the status phase), the USBADR will be programmed instantly at the correct time and meet the 2ms USB requirement. 24 1 read-write PERIODICLISTBASE Frame List Base Address Register UNION_154 0x154 32 0x00000000 0xFFFFF000 BASEADR BASEADR Base Address (Low). These bits correspond to memory address signals [31:12], respectively. Only used by the host controller. 12 20 read-write ASYNCLISTADDR Next Asynch.

This field may only reference a Queue Head (QH). Only used by the host controller. 5 27 read-write ENDPTLISTADDR Endpoint List Address Register UNION_158 0x158 32 0x00000000 0xFFFFF800 EPBASE EPBASE Endpoint List Pointer(Low). These bits correspond to memory address signals [31:11], respectively. This field will reference a list of up to 32 Queue Head (QH) (that is, one queue head per endpoint & direction). 11 21 read-write BURSTSIZE Programmable Burst Size Register 0x160 32 0x00000000 0x0000FFFF TXPBURST TXPBURST Programmable TX Burst Size. Default value is determined by TXBURST bits in n_HWTXBUF. This register represents the maximum length of a the burst in 32-bit words while moving data from system memory to the USB bus. 8 8 read-write RXPBURST RXPBURST Programmable RX Burst Size. Default value is determined by TXBURST bits in n_HWRXBUF. This register represents the maximum length of a the burst in 32-bit words while moving data from the USB bus to system memory. 0 8 read-write TXFILLTUNING TX FIFO Fill Tuning Register 0x164 32 0x00000000 0x003F1F7F TXFIFOTHRES TXFIFOTHRES FIFO Burst Threshold. (Read/Write) This register controls the number of data bursts that are posted to the TX latency FIFO in host mode before the packet begins on to the bus. The minimum value is 2 and this value should be a low as possible to maximize USB performance. A higher value can be used in systems with unpredictable latency and/or insufficient bandwidth where the FIFO may underrun because the data transferred from the latency FIFO to USB occurs before it can be replenished from system memory. This value is ignored if the Stream Disable bit in USB_n_USBMODE register is set. 16 6 read-write TXSCHHEALTH TXSCHHEALTH Scheduler Health Counter. (Read/Write To Clear) Table continues on the next page This register increments when the host controller fails to fill the TX latency FIFO to the level programmed by TXFIFOTHRES before running out of time to send the packet before the next Start-Of-Frame. This health counter measures the number of times this occurs to provide feedback to selecting a proper TXSCHOH. Writing to this register will clear the counter and this counter will max. at 31. 8 5 read-write TXSCHOH TXSCHOH Scheduler Overhead. (Read/Write) [Default = 0] This register adds an additional fixed offset to the schedule time estimator described above as Tff. As an approximation, the value chosen for this register should limit the number of back-off events captured in the TXSCHHEALTH to less than 10 per second in a highly utilized bus. Choosing a value that is too high for this register is not desired as it can needlessly reduce USB utilization. The time unit represented in this register is 1.267us when a device is connected in High-Speed Mode. The time unit represented in this register is 6.333us when a device is connected in Low/Full Speed Mode. Default value is '08h' for OTG controller core . 0 7 read-write ENDPTNAK Endpoint NAK Register 0x178 32 0x00000000 0xFFFFFFFF EPTN EPTN TX Endpoint NAK - R/WC. Each TX endpoint has 1 bit in this field. The bit is set when the device sends a NAK handshake on a received IN token for the corresponding endpoint. Bit [N] - Endpoint #[N], N is 0-7 16 16 read-write EPRN EPRN RX Endpoint NAK - R/WC. Each RX endpoint has 1 bit in this field. The bit is set when the device sends a NAK handshake on a received OUT or PING token for the corresponding endpoint. Bit [N] - Endpoint #[N], N is 0-7 0 16 read-write ENDPTNAKEN Endpoint NAK Enable Register 0x17c 32 0x00000000 0xFFFFFFFF EPTNE EPTNE TX Endpoint NAK Enable - R/W. Each bit is an enable bit for the corresponding TX Endpoint NAK bit. If this bit is set and the corresponding TX Endpoint NAK bit is set, the NAK Interrupt bit is set. Bit [N] - Endpoint #[N], N is 0-7 16 16 read-write EPRNE EPRNE RX Endpoint NAK Enable - R/W. Each bit is an enable bit for the corresponding RX Endpoint NAK bit. If this bit is set and the corresponding RX Endpoint NAK bit is set, the NAK Interrupt bit is set. Bit [N] - Endpoint #[N], N is 0-7 0 16 read-write PORTSC1 Port Status & Control 0x184 32 0x00000000 0x3DFF1FFF STS STS Serial Transceiver Select 1 Serial Interface Engine is selected 0 Parallel Interface signals is selected Serial Interface Engine can be used in combination with UTMI+/ULPI physical interface to provide FS/LS signaling instead of the parallel interface signals. When this bit is set '1b', serial interface engine will be used instead of parallel interface signals. 29 1 read-write PTW PTW Parallel Transceiver Width This bit has no effect if serial interface engine is used. 0 - Select the 8-bit UTMI interface [60MHz] 1 - Select the 16-bit UTMI interface [30MHz] 28 1 read-write PSPD PSPD Port Speed - Read Only. This register field indicates the speed at which the port is operating. 00 - Full Speed 01 - Low Speed 10 - High Speed 11 - Undefined 26 2 read-only PFSC PFSC Port Force Full Speed Connect - Read/Write. Default = 0b. When this bit is set to '1b', the port will be forced to only connect at Full Speed, It disables the chirp sequence that allows the port to identify itself as High Speed. 0 - Normal operation 1 - Forced to full speed 24 1 read-write PHCD PHCD PHY Low Power Suspend - Clock Disable (PLPSCD) - Read/Write. Default = 0b. When this bit is set to '1b', the PHY clock is disabled. Reading this bit will indicate the status of the PHY clock. NOTE: The PHY clock cannot be disabled if it is being used as the system clock. In device mode, The PHY can be put into Low Power Suspend when the device is not running (USBCMD Run/Stop=0b) or the host has signalled suspend (PORTSC1 SUSPEND=1b). PHY Low power suspend will be cleared automatically when the host initials resume. Before forcing a resume from the device, the device controller driver must clear this bit. In host mode, the PHY can be put into Low Power Suspend when the downstream device has been put into suspend mode or when no downstream device is connected. Low power suspend is completely under the control of software. 0 - Enable PHY clock 1 - Disable PHY clock 23 1 read-write WKOC WKOC Wake on Over-current Enable (WKOC_E) - Read/Write. Default = 0b. Writing this bit to a one enables the port to be sensitive to over-current conditions as wake-up events. This field is zero if Port Power(PORTSC1) is zero. 22 1 read-write WKDC WKDC Wake on Disconnect Enable (WKDSCNNT_E) - Read/Write. Default=0b. Writing this bit to a one enables the port to be sensitive to device disconnects as wake-up events. This field is zero if Port Power(PORTSC1) is zero or in device mode. 21 1 read-write WKCN WKCN Wake on Connect Enable (WKCNNT_E) - Read/Write. Default=0b. Writing this bit to a one enables the port to be sensitive to device connects as wake-up events. This field is zero if Port Power(PORTSC1) is zero or in device mode. 20 1 read-write PTC PTC Port Test Control - Read/Write. Default = 0000b. Refer to Port Test Mode for the operational model for using these test modes and the USB Specification Revision 2.0, Chapter 7 for details on each test mode. The FORCE_ENABLE_FS and FORCE ENABLE_LS are extensions to the test mode support specified in the EHCI specification. Writing the PTC field to any of the FORCE_ENABLE_{HS/FS/LS} values will force the port into the connected and enabled state at the selected speed. Writing the PTC field back to TEST_MODE_DISABLE will allow the port state machines to progress normally from that point. NOTE: Low speed operations are not supported as a peripheral device. Any other value than zero indicates that the port is operating in test mode. Value Specific Test 0000 - TEST_MODE_DISABLE 0001 - J_STATE 0010 - K_STATE 0011 - SE0 (host) / NAK (device) 0100 - Packet 0101 - FORCE_ENABLE_HS 0110 - FORCE_ENABLE_FS 0111 - FORCE_ENABLE_LS 1000-1111 - Reserved 16 4 read-write PP PP Port Power (PP)-Read/Write or Read Only. The function of this bit depends on the value of the Port Power Switching (PPC) field in the HCSPARAMS register. The behavior is as follows: PPC PP Operation 0 1b Read Only - Host controller does not have port power control switches. Each port is hard-wired to power. 1 1b/0b - Read/Write. OTG controller requires port power control switches. This bit represents the current setting of the switch (0=off, 1=on). When power is not available on a port (that is, PP equals a 0), the port is non-functional and will not report attaches, detaches, etc. When an over-current condition is detected on a powered port and PPC is a one, the PP bit in each affected port may be transitional by the host controller driver from a one to a zero (removing power from the port). This feature is implemented in all controller cores (PPC = 1). 12 1 read-write LS LS Line Status-Read Only. These bits reflect the current logical levels of the D+ (bit 11) and D- (bit 10) signal lines. In host mode, the use of linestate by the host controller driver is not necessary (unlike EHCI), because the port controller state machine and the port routing manage the connection of LS and FS. In device mode, the use of linestate by the device controller driver is not necessary. The encoding of the bits are: Bits [11:10] Meaning 00 - SE0 01 - K-state 10 - J-state 11 - Undefined 10 2 read-only HSP HSP High-Speed Port - Read Only. Default = 0b. When the bit is one, the host/device connected to the port is in high-speed mode and if set to zero, the host/device connected to the port is not in a high-speed mode. NOTE: HSP is redundant with PSPD(bit 27, 26) but remained for compatibility. 9 1 read-only PR PR Port Reset - Read/Write or Read Only. Default = 0b. In Host Mode: Read/Write. 1=Port is in Reset. 0=Port is not in Reset. Default 0. When software writes a one to this bit the bus-reset sequence as defined in the USB Specification Revision 2.0 is started. This bit will automatically change to zero after the reset sequence is complete. This behavior is different from EHCI where the host controller driver is required to set this bit to a zero after the reset duration is timed in the driver. In Device Mode: This bit is a read only status bit. Device reset from the USB bus is also indicated in the USBSTS register. 8 1 read-write SUSP SUSP Suspend - Read/Write or Read Only. Default = 0b. 1=Port in suspend state. 0=Port not in suspend state. In Host Mode: Read/Write. Port Enabled Bit and Suspend bit of this register define the port states as follows: Bits [Port Enabled, Suspend] Port State 0x Disable 10 Enable 11 Suspend When in suspend state, downstream propagation of data is blocked on this port, except for port reset. The blocking occurs at the end of the current transaction if a transaction was in progress when this bit was written to 1. In the suspend state, the port is sensitive to resume detection. Note that the bit status does not change until the port is suspended and that there may be a delay in suspending a port if there is a transaction currently in progress on the USB. The host controller will unconditionally set this bit to zero when software sets the Force Port Resume bit to zero. The host controller ignores a write of zero to this bit. If host software sets this bit to a one when the port is not enabled (that is, Port enabled bit is a zero) the results are undefined. This field is zero if Port Power(PORTSC1) is zero in host mode. In Device Mode: Read Only. In device mode this bit is a read only status bit. 7 1 read-write FPR FPR Force Port Resume -Read/Write. 1= Resume detected/driven on port. 0=No resume (K-state) detected driven on port. Default = 0. In Host Mode: Software sets this bit to one to drive resume signaling. The Host Controller sets this bit to one if a J-to-K transition is detected while the port is in the Suspend state. When this bit transitions to a one because a J-to-K transition is detected, the Port Change Detect bit in the USBSTS register is also set to one. This bit will automatically change to zero after the resume sequence is complete. This behavior is different from EHCI where the host controller driver is required to set this bit to a zero after the resume duration is timed in the driver. Note that when the Host controller owns the port, the resume sequence follows the defined sequence documented in the USB Specification Revision 2.0. The resume signaling (Full-speed 'K') is driven on the port as long as this bit remains a one. This bit will remain a one until the port has switched to the high-speed idle. Writing a zero has no effect because the port controller will time the resume operation, clear the bit the port control state switches to HS or FS idle. This field is zero if Port Power(PORTSC1) is zero in host mode. This bit is not-EHCI compatible. In Device mode: After the device has been in Suspend State for 5ms or more, software must set this bit to one to drive resume signaling before clearing. The Device Controller will set this bit to one if a J-to-K transition is detected while the port is in the Suspend state. The bit will be cleared when the device returns to normal operation. Also, when this bit wil be cleared because a K-to-J transition detected, the Port Change Detect bit in the USBSTS register is also set to one. 6 1 read-write OCC OCC Over-current Change-R/WC. Default=0. This bit is set '1b' by hardware when there is a change to Over-current Active. Software can clear this bit by writing a one to this bit position. 5 1 read-write OCA OCA Over-current Active-Read Only. Default 0. This bit will automatically transition from one to zero when the over current condition is removed. 0 - This port does not have an over-current condition. 1 - This port currently has an over-current condition 4 1 read-only PEC PEC Port Enable/Disable Change-R/WC. 1=Port enabled/disabled status has changed. 0=No change. Default = 0. In Host Mode: For the root hub, this bit is set to a one only when a port is disabled due to disconnect on the port or due to the appropriate conditions existing at the EOF2 point (See Chapter 11 of the USB Specification). Software clears this by writing a one to it. This field is zero if Port Power(PORTSC1) is zero. In Device mode: The device port is always enabled, so this bit is always '0b'. 3 1 read-write PE PE Port Enabled/Disabled-Read/Write. 1=Enable. 0=Disable. Default 0. In Host Mode: Ports can only be enabled by the host controller as a part of the reset and enable. Software cannot enable a port by writing a one to this field. Ports can be disabled by either a fault condition (disconnect event or other fault condition) or by the host software. Note that the bit status does not change until the port state actually changes. There may be a delay in disabling or enabling a port due to other host controller and bus events. When the port is disabled, (0b) downstream propagation of data is blocked except for reset. This field is zero if Port Power(PORTSC1) is zero in host mode. In Device Mode: The device port is always enabled, so this bit is always '1b'. 2 1 read-write CSC CSC Connect Status Change-R/WC. 1 =Change in Current Connect Status. 0=No change. Default 0. In Host Mode: Indicates a change has occurred in the port's Current Connect Status. The host/device controller sets this bit for all changes to the port device connect status, even if system software has not cleared an existing connect status change. For example, the insertion status changes twice before system software has cleared the changed condition, hub hardware will be 'setting' an already-set bit (that is, the bit will remain set). Software clears this bit by writing a one to it. This field is zero if Port Power(PORTSC1) is zero in host mode. In Device Mode: This bit is undefined in device controller mode. 1 1 read-write CCS CCS Current Connect Status-Read Only. In Host Mode: 1=Device is present on port. 0=No device is present. Default = 0. This value reflects the current state of the port, and may not correspond directly to the event that caused the Connect Status Change bit (Bit 1) to be set. This field is zero if Port Power(PORTSC1) is zero in host mode. In Device Mode: 1=Attached. 0=Not Attached. Default=0. A one indicates that the device successfully attached and is operating in either high speed or full speed as indicated by the High Speed Port bit in this register. A zero indicates that the device did not attach successfully or was forcibly disconnected by the software writing a zero to the Run bit in the USBCMD register. It does not state the device being disconnected or Suspended. 0 1 read-write OTGSC On-The-Go Status & control Register 0x1a4 32 0x00000000 0x07070723 ASVIE ASVIE A Session Valid Interrupt Enable - Read/Write. 26 1 read-write AVVIE AVVIE A VBus Valid Interrupt Enable - Read/Write. Setting this bit enables the A VBus valid interrupt. 25 1 read-write IDIE IDIE USB ID Interrupt Enable - Read/Write. Setting this bit enables the USB ID interrupt. 24 1 read-write ASVIS ASVIS A Session Valid Interrupt Status - Read/Write to Clear. This bit is set when VBus has either risen above or fallen below the A session valid threshold. Software must write a one to clear this bit. 18 1 read-write AVVIS AVVIS A VBus Valid Interrupt Status - Read/Write to Clear. This bit is set when VBus has either risen above or fallen below the VBus valid threshold on an A device. Software must write a one to clear this bit. 17 1 read-write IDIS IDIS USB ID Interrupt Status - Read/Write. This bit is set when a change on the ID input has been detected. Software must write a one to clear this bit. 16 1 read-write ASV ASV A Session Valid - Read Only. Indicates VBus is above the A session valid threshold. 10 1 read-only AVV AVV A VBus Valid - Read Only. Indicates VBus is above the A VBus valid threshold. 9 1 read-only ID ID USB ID - Read Only. 0 = A device, 1 = B device 8 1 read-only IDPU IDPU ID Pullup - Read/Write This bit provide control over the ID pull-up resistor; 0 = off, 1 = on [default]. When this bit is 0, the ID input will not be sampled. 5 1 read-write VC VC VBUS Charge - Read/Write. Setting this bit causes the VBus line to be charged. This is used for VBus pulsing during SRP. 1 1 read-write VD VD VBUS_Discharge - Read/Write. Setting this bit causes VBus to discharge through a resistor. 0 1 read-write USBMODE USB Device Mode Register 0x1a8 32 0x00000000 0x0000001F SDIS SDIS Stream Disable Mode. (0 - Inactive [default]; 1 - Active) Device Mode: Setting to a '1' disables double priming on both RX and TX for low bandwidth systems. This mode ensures that when the RX and TX buffers are sufficient to contain an entire packet that the standard double buffering scheme is disabled to prevent overruns/underruns in bandwidth limited systems. Note: In High Speed Mode, all packets received are responded to with a NYET handshake when stream disable is active. Host Mode: Setting to a '1' ensures that overruns/underruns of the latency FIFO are eliminated for low bandwidth systems where the RX and TX buffers are sufficient to contain the entire packet. Enabling stream disable also has the effect of ensuring the TX latency is filled to capacity before the packet is launched onto the USB. NOTE: Time duration to pre-fill the FIFO becomes significant when stream disable is active.

In device mode, this bit controls behavior of the setup lock mechanism. See Control Endpoint Operation Model . 0 - Setup Lockouts On (default); 1 - Setup Lockouts Off. DCD requires use of Setup Data Buffer Tripwire in USBCMD. 3 1 read-write ES ES Endian Select - Read/Write. This bit can change the byte alignment of the transfer buffers to match the host microprocessor. The bit fields in the microprocessor interface and the data structures are unaffected by the value of this bit because they are based upon the 32-bit word. Bit Meaning 0 - Little Endian [Default] 1 - Big Endian 2 1 read-write CM CM Controller Mode - R/WO. Controller mode is defaulted to the proper mode for host only and device only implementations. For those designs that contain both host & device capability, the controller defaults to an idle state and needs to be initialized to the desired operating mode after reset. For combination host/ device controllers, this register can only be written once after reset. If it is necessary to switch modes, software must reset the controller by writing to the RESET bit in the USBCMD register before reprogramming this register. For OTG controller core, reset value is '00b'. 00 - Idle [Default for combination host/device] 01 - Reserved 10 - Device Controller [Default for device only controller] 11 - Host Controller [Default for host only controller] 0 2 read-write ENDPTSETUPSTAT Endpoint Setup Status Register 0x1ac 32 0x00000000 0x0000FFFF ENDPTSETUPSTAT ENDPTSETUPSTAT Setup Endpoint Status. For every setup transaction that is received, a corresponding bit in this register is set to one. Software must clear or acknowledge the setup transfer by writing a one to a respective bit after it has read the setup data from Queue head. The response to a setup packet as in the order of operations and total response time is crucial to limit bus time outs while the setup lock out mechanism is engaged. This register is only used in device mode. 0 16 read-write ENDPTPRIME Endpoint Prime Register 0x1b0 32 0x00000000 0xFFFFFFFF PETB PETB Prime Endpoint Transmit Buffer - R/WS. For each endpoint a corresponding bit is used to request that a buffer is prepared for a transmit operation in order to respond to a USB IN/INTERRUPT transaction. Software should write a one to the corresponding bit when posting a new transfer descriptor to an endpoint queue head. Hardware automatically uses this bit to begin parsing for a new transfer descriptor from the queue head and prepare a transmit buffer. Hardware clears this bit when the associated endpoint(s) is (are) successfully primed. NOTE: These bits are momentarily set by hardware during hardware re-priming operations when a dTD is retired, and the dQH is updated. PETB[N] - Endpoint #N, N is in 0..7 16 16 read-write PERB PERB Prime Endpoint Receive Buffer - R/WS. For each endpoint, a corresponding bit is used to request a buffer prepare for a receive operation for when a USB host initiates a USB OUT transaction. Software should write a one to the corresponding bit whenever posting a new transfer descriptor to an endpoint queue head. Hardware automatically uses this bit to begin parsing for a new transfer descriptor from the queue head and prepare a receive buffer.

One bit for each endpoint indicates status of the respective endpoint buffer. This bit is set to one by the hardware as a response to receiving a command from a corresponding bit in the ENDPTPRIME register. There is always a delay between setting a bit in the ENDPTPRIME register and endpoint indicating ready. This delay time varies based upon the current USB traffic and the number of bits set in the ENDPRIME register. Buffer ready is cleared by USB reset, by the USB DMA system, or through the ENDPTFLUSH register. NOTE: These bits are momentarily cleared by hardware during hardware endpoint re-priming operations when a dTD is retired, and the dQH is updated.

This setting is available on the sd_vdd1_on output of SDXC so that it can be used to control the VDD1 power supply of the card. Before setting this bit, the SD Host Driver sets the SD Bus Voltage Select bit. If the Host Controller detects a No Card state, this bit is cleared. In SD mode, if this bit is cleared, the Host Controller stops the SD Clock by clearing the SD_CLK_EN bit in the SYS_CTRL register.

It bit is also used to initialize a UHS-II command circuit. This reset is effective only for a command issuing circuit (including response error statuses related to Command Inhibit (CMD) control) and does not affect the data transfer circuit. Host Controller can continue data transfer even after this reset is executed while handling subcommand-response errors. The following registers and bits are cleared by this bit: Present State register : Command Inhibit (CMD) bit Normal Interrupt Status register : Command Complete bit Error Interrupt Status : Response error statuses related to Command Inhibit (CMD) bit Values: 0x0 (FALSE): Work 0x1 (TRUE): Reset 25 1 read-write SW_RST_ALL Software Reset For All This reset affects the entire Host Controller except for the card detection circuit. During its initialization, the Host Driver sets this bit to 1 to reset the Host Controller. All registers are reset except the capabilities register. If this bit is set to 1, the Host Driver must issue reset command and reinitialize the card. Values: 0x0 (FALSE): Work 0x1 (TRUE): Reset 24 1 read-write TOUT_CNT Data Timeout Counter Value. This value determines the interval by which DAT line timeouts are detected. The Timeout clock frequency is generated by dividing the base clock TMCLK value by this value. When setting this register, prevent inadvertent timeout events by clearing the Data Timeout Error Status Enable (in the Error Interrupt Status Enable register). The values for these bits are: 0xF : Reserved 0xE : TMCLK x 2^27 ......... 0x1 : TMCLK x 2^14 0x0 : TMCLK x 2^13 Note: During a boot operating in an eMMC mode, an application must configure the boot data timeout value (approximately 1 sec) in this bit. 16 4 read-write FREQ_SEL SDCLK/RCLK Frequency Select These bits are used to select the frequency of the SDCLK signal. These bits depend on setting of Preset Value Enable in the Host Control 2 register. If Preset Value Enable = 0, these bits are set by the Host Driver. If Preset Value Enable = 1, these bits are automatically set to a value specified in one of the Preset Value register. The value is reflected on the lower 8-bit of the card_clk_freq_selsignal. 10-bit Divided Clock Mode: 0x3FF : 1/2046 Divided clock ..........

The value is reflected on the upper 2 bits of the card_clk_freq_sel signal. 6 2 read-write CLK_GEN_SELECT Clock Generator Select This bit is used to select the clock generator mode in SDCLK/RCLK Frequency Select. If Preset Value Enable = 0, this bit is set by the Host Driver. If Preset Value Enable = 1, this bit is automatically set to a value specified in one of the Preset Value registers. The value is reflected on the card_clk_gen_sel signal. Values: 0x0 (FALSE): Divided Clock Mode 0x1 (TRUE): Programmable Clock Mode 5 1 read-write PLL_ENABLE PLL Enable This bit is used to activate the PLL (applicable when Host Version 4 Enable = 1). When Host Version 4 Enable = 0, INTERNAL_CLK_EN bit may be used to activate PLL. The value is reflected on the card_clk_en signal. Note: If this bit is not used to to active the PLL when Host Version 4 Enable = 1, it is recommended to set this bit to '1' . Values: 0x0 (FALSE): PLL is in low power mode 0x1 (TRUE): PLL is enabled 3 1 read-write SD_CLK_EN SD/eMMC Clock Enable This bit stops the SDCLK or RCLK when set to 0.

Values: 0x0 (FALSE): Not Ready 0x1 (TRUE): Ready 1 1 read-write INTERNAL_CLK_EN Internal Clock Enable This bit is set to 0 when the Host Driver is not using the Host Controller or the Host Controller awaits a wakeup interrupt. The Host Controller must stop its internal clock to enter a very low power state. However, registers can still be read and written to. The value is reflected on the intclk_en signal. Note: If this bit is not used to control the internal clock (base clock and master clock), it is recommended to set this bit to '1' . Values: 0x0 (FALSE): Stop 0x1 (TRUE): Oscillate 0 1 read-write INT_STAT No description available 0x30 32 0x00000000 0x1FFFF1FF BOOT_ACK_ERR Boot Acknowledgment Error This bit is set when there is a timeout for boot acknowledgement or when detecting boot ack status having a value other than 010. This is applicable only when boot acknowledgement is expected in eMMC mode. In SD/UHS-II mode, this bit is irrelevant. 28 1 read-write RESP_ERR Response Error Host Controller Version 4.00 supports response error check function to avoid overhead of response error check by Host Driver during DMA execution. If Response Error Check Enable is set to 1 in the Transfer Mode register, Host Controller Checks R1 or R5 response. If an error is detected in a response, this bit is set to 1.This is applicable in SD/eMMC mode. Values: 0x0 (FALSE): No error 0x1 (TRUE): Error 27 1 read-write TUNING_ERR Tuning Error This bit is set when an unrecoverable error is detected in a tuning circuit except during the tuning procedure (occurrence of an error during tuning procedure is indicated by Sampling Clock Select in the Host Control 2 register). By detecting Tuning Error, Host Driver needs to abort a command executing and perform tuning. To reset tuning circuit, Sampling Clock Select is set to 0 before executing tuning procedure. The Tuning Error is higher priority than the other error interrupts generated during data transfer. By detecting Tuning Error, the Host Driver must discard data transferred by a current read/write command and retry data transfer after the Host Controller retrieved from the tuning circuit error. This is applicable in SD/eMMC mode. Values: 0x0 (FALSE): No error 0x1 (TRUE): Error 26 1 read-write ADMA_ERR ADMA Error This bit is set when the Host Controller detects error during ADMA-based data transfer. The error could be due to following reasons: Error response received from System bus (Master I/F) ADMA3,ADMA2 Descriptors invalid CQE Task or Transfer descriptors invalid When the error occurs, the state of the ADMA is saved in the ADMA Error Status register. In eMMC CQE mode: The Host Controller generates this Interrupt when it detects an invalid descriptor data (Valid=0) at the ST_FDS state. ADMA Error State in the ADMA Error Status indicates that an error has occurred in ST_FDS state. The Host Driver may find that Valid bit is not set at the error descriptor. Values: 0x0 (FALSE): No error 0x1 (TRUE): Error 25 1 read-write AUTO_CMD_ERR Auto CMD Error This error status is used by Auto CMD12 and Auto CMD23 in SD/eMMC mode. This bit is set when detecting that any of the bits D00 to D05 in Auto CMD Error Status register has changed from 0 to 1. D07 is effective in case of Auto CMD12. Auto CMD Error Status register is valid while this bit is set to 1 and may be cleared by clearing of this bit. Values: 0x0 (FALSE): No error 0x1 (TRUE): Error 24 1 read-write CUR_LMT_ERR Current Limit Error By setting the SD Bus Power bit in the Power Control register, the Host Controller is requested to supply power for the SD Bus. If the Host Controller supports the Current Limit function, it can be protected from an illegal card by stopping power supply to the card in which case this bit indicates a failure status. A reading of 1 for this bit means that the Host Controller is not supplying power to the SD card due to some failure. A reading of 0 for this bit means that the Host Controller is supplying power and no error has occurred. The Host Controller may require some sampling time to detect the current limit. SDXC Host Controller does not support this function, this bit is always set to 0. Values: 0x0 (FALSE): No error 0x1 (TRUE): Power Fail 23 1 read-write DATA_END_BIT_ERR Data End Bit Error This error occurs in SD/eMMC mode either when detecting 0 at the end bit position of read data that uses the DAT line or at the end bit position of the CRC status. Values: 0x0 (FALSE): No error 0x1 (TRUE): Error 22 1 read-write DATA_CRC_ERR Data CRC Error This error occurs in SD/eMMC mode when detecting CRC error when transferring read data which uses the DAT line, when detecting the Write CRC status having a value of other than 010 or when write CRC status timeout. Values: 0x0 (FALSE): No error 0x1 (TRUE): Error 21 1 read-write DATA_TOUT_ERR Data Timeout Error This bit is set in SD/eMMC mode when detecting one of the following timeout conditions: Busy timeout for R1b, R5b type Busy timeout after Write CRC status Write CRC Status timeout Read Data timeout Values: 0x0 (FALSE): No error 0x1 (TRUE): Time out 20 1 read-write CMD_IDX_ERR Command Index Error This bit is set if a Command Index error occurs in the command respons in SD/eMMC mode. Values: 0x0 (FALSE): No error 0x1 (TRUE): Error 19 1 read-write CMD_END_BIT_ERR Command End Bit Error This bit is set when detecting that the end bit of a command response is 0 in SD/eMMC mode. Values: 0x0 (FALSE): No error 0x1 (TRUE): End Bit error generated 18 1 read-write CMD_CRC_ERR Command CRC Error Command CRC Error is generated in SD/eMMC mode for following two cases. If a response is returned and the Command Timeout Error is set to 0 (indicating no timeout), this bit is set to 1 when detecting a CRC error in the command response. The Host Controller detects a CMD line conflict by monitoring the CMD line when a command is issued. If the Host Controller drives the CMD line to 1 level, but detects 0 level on the CMD line at the next SD clock edge, then the Host Controller aborts the command (stop driving CMD line) and set this bit to 1. The Command Timeout Error is also set to 1 to distinguish a CMD line conflict. Values: 0x0 (FALSE): No error 0x1 (TRUE): CRC error generated 17 1 read-write CMD_TOUT_ERR Command Timeout Error In SD/eMMC Mode,this bit is set only if no response is returned within 64 SD clock cycles from the end bit of the command. If the Host Controller detects a CMD line conflict, along with Command CRC Error bit, this bit is set to 1, without waiting for 64 SD/eMMC card clock cycles. Values: 0x0 (FALSE): No error 0x1 (TRUE): Time out 16 1 read-write ERR_INTERRUPT Error Interrupt If any of the bits in the Error Interrupt Status register are set, then this bit is set.

Values: 0x1 (WEN_SET): Sets INTC_TH_WEN 0x0 (WEN_CLR): Clears INTC_TH_WEN 15 1 write-only INTC_TH Interrupt Coalescing Counter Threshold filed Software uses this field to configure the number of task completions (only tasks with INT=0 in the Task Descriptor), which are required in order to generate an interrupt. Counter Operation: As data transfer tasks with INT=0 complete, they are counted by CQE. The counter is reset by software during the interrupt service routine. The counter stops counting when it reaches the value configured in INTC_TH, and generates interrupt. 0x0: Interrupt coalescing feature disabled 0x1: Interrupt coalescing interrupt generated after 1 task when INT=0 completes 0x2: Interrupt coalescing interrupt generated after 2 tasks when INT=0 completes ........ 0x1f: Interrupt coalescing interrupt generated after 31 tasks when INT=0 completes To write to this field, the INTC_TH_WEN bit must be set during the same write operation. 8 5 write-only TOUT_VAL_WEN When software writes 1 to this bit, the value TOUT_VAL is updated with the contents written on the same cycle.

Timer Operation: The timer is reset by software during the interrupt service routine. It starts running when the first data transfer task with INT=0 is completed, after the timer was reset. When the timer reaches the value configured in ICTOVAL field, it generates an interrupt and stops. The timer's unit is equal to 1024 clock periods of the clock whose frequency is specified in the Internal Timer Clock Frequency field CQCAP register. 0x0: Timer is disabled. Timeout-based interrupt is not generated 0x1: Timeout on 01x1024 cycles of timer clock frequency 0x2: Timeout on 02x1024 cycles of timer clock frequency ........ 0x7f: Timeout on 127x1024 cycles of timer clock frequency In order to write to this field, the TOUT_VAL_WEN bit must be set at the same write operation. 0 7 read-write CQTDLBA No description available 0x1a0 32 0x00000000 0xFFFFFFFF TDLBA This register stores the LSB bits (31:0) of the byte address of the head of the Task Descriptor List in system memory. The size of the task descriptor list is 32 * (Task Descriptor size + Transfer Descriptor size) as configured by the host driver. This address is set on 1 KB boundary. The lower 10 bits of this register are set to 0 by the software and are ignored by CQE 0 32 read-write CQTDBR No description available 0x1a8 32 0x00000000 0xFFFFFFFF DBR The software configures TDLBA and TDLBAU, and enable CQE in CQCFG before using this register. Writing 1 to bit n of this register triggers CQE to start processing the task encoded in slot n of the TDL. Writing 0 by the software does not have any impact on the hardware, and does not change the value of the register bit. CQE always processes tasks according to the order submitted to the list by CQTDBR write transactions. CQE processes Data Transfer tasks by reading the Task Descriptor and sending QUEUED_TASK_PARAMS (CMD44) and QUEUED_TASK_ADDRESS (CMD45) commands to the device. CQE processes DCMD tasks (in slot #31, when enabled) by reading the Task Descriptor, and generating the command encoded by its index and argument. The corresponding bit is cleared to 0 by CQE in one of the following events: A task execution is completed (with success or error). The task is cleared using CQTCLR register. All tasks are cleared using CQCTL register. CQE is disabled using CQCFG register. Software may initiate multiple tasks at the same time (batch submission) by writing 1 to multiple bits of this register in the same transaction. In the case of batch submission, CQE processes the tasks in order of the task index, starting with the lowest index. If one or more tasks in the batch are marked with QBR, the ordering of execution is based on said processing order. 0 32 read-write CQTCN No description available 0x1ac 32 0x00000000 0xFFFFFFFF TCN Task Completion Notification Each of the 32 bits are bit mapped to the 32 tasks. Bit-N(1): Task-N has completed execution (with success or errors) Bit-N(0): Task-N has not completed, could be pending or not submitted. On task completion, software may read this register to know tasks that have completed. After reading this register, software may clear the relevant bit fields by writing 1 to the corresponding bits. 0 32 read-write CQDQS No description available 0x1b0 32 0x00000000 0xFFFFFFFF DQS Device Queue Status Each of the 32 bits are bit mapped to the 32 tasks. Bit-N(1): Device has marked task N as ready for execution Bit-N(0): Task-N is not ready for execution. This task could be pending in device or not submitted. Host controller updates this register with response of the Device Queue Status command. 0 32 read-write CQDPT No description available 0x1b4 32 0x00000000 0xFFFFFFFF DPT Device-Pending Tasks Each of the 32 bits are bit mapped to the 32 tasks. Bit-N(1): Task-N has been successfully queued into the device and is awaiting execution Bit-N(0): Task-N is not yet queued. Bit n of this register is set if and only if QUEUED_TASK_PARAMS (CMD44) and QUEUED_TASK_ADDRESS (CMD45) were sent for this specific task and if this task has not been executed. The controller sets this bit after receiving a successful response for CMD45. CQE clears this bit after the task has completed execution. Software reads this register in the task-discard procedure to determine if the task is queued in the device 0 32 read-write CQTCLR No description available 0x1b8 32 0x00000000 0xFFFFFFFF TCLR Writing 1 to bit n of this register orders CQE to clear a task that the software has previously issued. This bit can only be written when CQE is in Halt state as indicated in CQCFG register Halt bit. When software writes 1 to a bit in this register, CQE updates the value to 1, and starts clearing the data structures related to the task. CQE clears the bit fields (sets a value of 0) in CQTCLR and in CQTDBR once the clear operation is complete. Software must poll on the CQTCLR until it is leared to verify that a clear operation was done. 0 32 read-write CQSSC1 No description available 0x1c0 32 0x00000000 0x000FFFFF SQSCMD_BLK_CNT This field indicates when SQS CMD is sent while data transfer is in progress. A value of 'n' indicates that CQE sends status command on the CMD line, during the transfer of data block BLOCK_CNTn, on the data lines, where BLOCK_CNT is the number of blocks in the current transaction. 0x0: SEND_QUEUE_STATUS (CMD13) command is not sent during the transaction. Instead, it is sent only when the data lines are idle. 0x1: SEND_QUEUE_STATUS command is to be sent during the last block of the transaction. 0x2: SEND_QUEUE_STATUS command when last 2 blocks are pending. 0x3: SEND_QUEUE_STATUS command when last 3 blocks are pending. ........ 0xf: SEND_QUEUE_STATUS command when last 15 blocks are pending. Should be programmed only when CQCFG.CQ_EN is 0 16 4 read-write SQSCMD_IDLE_TMR This field configures the polling period to be used when using periodic SEND_QUEUE_STATUS (CMD13) polling. Periodic polling is used when tasks are pending in the device, but no data transfer is in progress. When a SEND_QUEUE_STATUS response indicates that no task is ready for execution, CQE counts the configured time until it issues the next SEND_QUEUE_STATUS. Timer units are clock periods of the clock whose frequency is specified in the Internal Timer Clock Frequency field CQCAP register. The minimum value is 0001h (1 clock period) and the maximum value is FFFFh (65535 clock periods). For example, a CQCAP field value of 0 indicates a 19.2 MHz clock frequency (period = 52.08 ns). If the setting in CQSSC1.CIT is 1000h, the calculated polling period is 4096*52.08 ns= 213.33 us. Should be programmed only when CQCFG.CQ_EN is '0' 0 16 read-write CQSSC2 No description available 0x1c4 32 0x00000000 0x0000FFFF SQSCMD_RCA This field provides CQE with the contents of the 16-bit RCA field in SEND_QUEUE_STATUS (CMD13) command argument. CQE copies this field to bits 31:16 of the argument when transmitting SEND_ QUEUE_STATUS (CMD13) command. 0 16 read-write CQCRDCT No description available 0x1c8 32 0x00000000 0xFFFFFFFF DCMD_RESP This register contains the response of the command generated by the last direct command (DCMD) task that was sent.

This bit is used as an interrupt mask on the device status filed that is received in R1/R1b responses. 1: When a R1/R1b response is received, with a bit i in the device status set, a RED interrupt is generated. 0: When a R1/R1b response is received, bit i in the device status is ignored. The reset value of this register is set to trigger an interrupt on all "Error" type bits in the device status. Note: Responses to CMD13 (SQS) encode the QSR so that they are ignored by this logic. 0 32 read-write CQTERRI No description available 0x1d4 32 0x00000000 0x1F3F9F3F TRANS_ERR_TASKID This field captures the ID of the task that was executed and whose data transfer has errors. 24 5 read-only TRANS_ERR_CMD_INDX This field captures the index of the command that was executed and whose data transfer has errors. 16 6 read-only RESP_ERR_FIELDS_VALID This bit is updated when an error is detected while a command transaction was in progress.

Therefore, the bit[3] as well as the bit[2:0] must be set to an appropriate value which is considered both the Address Mirroring of UDIMMs/RDIMMs and the Output Inversion of RDIMMs. Value After Reset: 0x0 Exists: Always 12 4 read-write MR_RANK Description: Controls which rank is accessed by MRCTRL0.mr_wr. Normally, it is desired to access all ranks, so all bits should be set to 1. However, for multi-rank UDIMMs/RDIMMs which implement address mirroring, it may be necessary to access ranks individually. Examples (assume uMCTL2 is configured for 4 ranks): 0x1 - select rank 0 only 0x2 - select rank 1 only 0x5 - select ranks 0 and 2 0xA - select ranks 1 and 3 0xF - select ranks 0, 1, 2 and 3 Value After Reset: "(MEMC_NUM_RANKS==4) ? 0xF :((MEMC_NUM_RANKS==2) ? 0x3 : 0x1)" Exists: Always 4 4 read-write MRCTRL1 Description: Mode Register Read/Write Control Register 1 0x14 32 0x00000000 0x0003FFFF MR_DATA Description: Mode register write data for all non- LPDDR2/non-LPDDR3 modes.

A critical refresh is to be issued before this threshold is reached. It is recommended that this not be changed from the default value, currently shown as 0x2. It must always be less than internally used t_rfc_nom_x32. Note that, in LPDDR2/LPDDR3, internally used t_rfc_nom_x32 may be equal to RFSHTMG.t_rfc_nom_x32>>2 if derating is enabled (DERATEEN.derate_enable=1). Otherwise, internally used t_rfc_nom_x32 will be equal to RFSHTMG.t_rfc_nom_x32. Unit: Multiples of 32 clocks.

A speculative refresh is a refresh performed at a time when refresh would be useful, but before it is absolutely required. When the SDRAM bus is idle for a period of time determined by this RFSHCTL0.refresh_to_x32 and the refresh timer has expired at least once since the last refresh, then a speculative refresh is performed. Speculative refreshes continues successively until there are no refreshes pending or until new reads or writes are issued to the uMCTL2. FOR PERFORMANCE ONLY. Value After Reset: 0x10 Exists: Always 12 5 read-write REFRESH_BURST Description: The programmed value + 1 is the number of refresh timeouts that is allowed to accumulate before traffic is blocked and the refreshes are forced to execute. Closing pages to perform a refresh is a one-time penalty that must be paid for each group of refreshes. Therefore, performing refreshes in a burst reduces the per-refresh penalty of these page closings. Higher numbers for RFSHCTL.refresh_burst slightly increases utilization; lower numbers decreases the worst-case latency associated with refreshes. 0 - single refresh 1 - burst-of-2 refresh 7 - burst-of-8 refresh For information on burst refresh feature refer to section 3.9 of DDR2 JEDEC specification - JESD79-2F.pdf. For DDR2/3, the refresh is always per-rank and not per- bank. The rank refresh can be accumulated over 8*tREFI cycles using the burst refresh feature. In DDR4 mode, according to Fine Granuarity feature, 8 refreshes can be postponed in 1X mode, 16 refreshes in 2X mode and 32 refreshes in 4X mode. If using PHY-initiated updates, care must be taken in the setting of RFSHCTL0.refresh_burst, to ensure that tRFCmax is not violated due to a PHY-initiated update occurring shortly before a refresh burst was due. In this situation, the refresh burst will be delayed until the PHY- initiated update is complete.

The value is automatically updated when exiting soft reset, so it does not need to be toggled initially. Value After Reset: 0x0 Exists: Always 1 1 read-write DIS_AUTO_REFRESH Description: When '1', disable auto-refresh generated by the uMCTL2. When auto-refresh is disabled, the SoC core must generate refreshes using the registers reg_ddrc_rank0_refresh, reg_ddrc_rank1_refresh, reg_ddrc_rank2_refresh and reg_ddrc_rank3_refresh. When dis_auto_refresh transitions from 0 to 1, any pending refreshes are immediately scheduled by the uMCTL2.

In DDR4 mode, tREFI value is different depending on the refresh mode. The user should program the appropriate value from the spec based on the value programmed in the refresh mode register.

Some UDIMMs and DDR4 RDIMMs implement address mirroring for odd ranks, which means that the following address, bank address and bank group bits are swapped: (A3, A4), (A5, A6), (A7, A8), (BA0, BA1) and also (A11, A13), (BG0, BG1) for the DDR4. Setting this bit ensures that, for mode register accesses during the automatic initialization routine, these bits are swapped within the uMCTL2 to compensate for this UDIMM/RDIMM swapping. In addition to the automatic initialization routine, in case of DDR4 UDIMM/RDIMM, they are swapped during the automatic MRS access to enable/disable of a particular DDR4 feature. Note: This has no effect on the address of any other memory accesses, or of software-driven mode register accesses. This is not supported for mDDR, LPDDR2 or LPDDR3 SDRAMs. Note: In case of x16 DDR4 DIMMs, BG1 output of MRS for the odd ranks is same as BG0 because BG1 is invalid, hence dimm_dis_bg_mirroring register must be set to 1. 1 - For odd ranks, implement address mirroring for MRS commands to during initialization and for any automatic DDR4 MRS commands (to be used if UDIMM/RDIMM implements address mirroring) 0 - Do not implement address mirroring Value After Reset: 0x0 Exists: Always 1 1 read-write DIMM_STAGGER_CS_EN Description: Staggering enable for multi-rank accesses (for multi-rank UDIMM and RDIMM implementations only).

Indicates the number of clocks of gap in data responses when performing consecutive writes to different ranks. This is used to switch the delays in the PHY to match the rank requirements. The value programmed in this register takes care of the ODT switch off timing requirement when switching ranks during writes.

Indicates the number of clocks of gap in data responses when performing consecutive reads to different ranks. This is used to switch the delays in the PHY to match the rank requirements. The value programmed in this register takes care of the ODT switch off timing requirement when switching ranks during reads. For configurations with MEMC_FREQ_RATIO=2, program this to (N/2) and round it up to the next integer value. N is value required by PHY, in terms of PHY clocks. Value After Reset: 0x6 Exists: MEMC_NUM_RANKS>1 4 4 read-write MAX_RANK_RD Description: Only present for multi-rank configurations. Background: Reads to the same rank can be performed back-to-back. Reads to different ranks require additional gap dictated by the register RANKCTL.diff_rank_rd_gap. This is to avoid possible data bus contention as well as to give PHY enough time to switch the delay when changing ranks. The uMCTL2 arbitrates for bus access on a cycle-by-cycle basis; therefore after a read is scheduled, there are few clock cycles (determined by the value on diff_rank_rd_gap register) in which only reads from the same rank are eligible to be scheduled. This prevents reads from other ranks from having fair access to the data bus. This parameter represents the maximum number of reads that can be scheduled consecutively to the same rank. After this number is reached, a delay equal to RANKCTL.diff_rank_rd_gap is inserted by the scheduler to allow all ranks a fair opportunity to be scheduled. Higher numbers increase bandwidth utilization, lower numbers increase fairness. This feature can be DISABLED by setting this register to 0. When set to 0, the Controller will stay on the same rank as long as commands are available for it. Minimum programmable value is 0 (feature disabled) and maximum programmable value is 0xF. Feature limitation: max_rank_rd feature works as described only in the mode in which one command at the DDRC input results in one DFI command at the output. An example of this mode is: BL8 hardware configuration (MEMC_BURST_LENGTH=8) and Full bus width mode (MSTR.data_bus_width=2'b00) and BL8 mode of operation (MSTR.burst_rdwr=4'b0100). In modes where single HIF command results in multiple DFI commands (eg: Half Bus Width, BL4 etc.), the same rank commands would be serviced for as long as they are available, which is equivalent to this feature being disabled.

Setting this to maximum value allocates all entries to low priority transaction store.

The last read or write command in the CAM with a bank and page hit will be executed with auto-precharge if SCHED1.pageclose_timer=0. Even if this register set to 1 and SCHED1.pageclose_timer is set to 0, explicit precharge (and not auto-precharge) may be issued in some cases where there is a mode switch between Write and Read or between LPR and HPR. The Read and Write commands that are executed as part of the ECC scrub requests are also executed without auto-precharge. If false, the bank remains open until there is a need to close it (to open a different page, or for page timeout or refresh timeout) - also known as open page policy. The open page policy can be overridden by setting the per-command-autopre bit on the HIF interface (co_ih_rxcmd_autopre). The pageclose feature provids a midway between Open and Close page policies.

It only has meaning if SCHED.pageclose==1. If SCHED.pageclose==1 and pageclose_timer==0, then an auto-precharge may be scheduled for last read or write command in the CAM with a bank and page hit. Note, sometimes an explicit precharge is scheduled instead of the auto-precharge. See SCHED.pageclose for details of when this may happen. If SCHED.pageclose==1 and pageclose_timer>0, then an auto-precharge is not scheduled for last read or write command in the CAM with a bank and page hit. Instead, a timer is started, with pageclose_timer as the initial value. There is a timer on a per bank basis. The timer decrements unless the next read or write in the CAM to a bank is a page hit. It gets reset to pageclose_timer value if the next read or write in the CAM to a bank is a page hit. Once the timer has reached zero, an explcit precharge will be attempted to be scheduled.

These counters will be parallel loaded after reset, or after each grant to the corresponding port. The aging counters down-count every clock cycle where the port is requesting but not granted. The higher significant 5-bits of the read aging counter sets the priority of the read channel of a given port. Port's priority will increase as the higher significant 5-bits of the counter starts to decrease.

For multi-port configurations, the aging counters cannot be used to set port priorities when external dynamic priority inputs (arqos) are enabled (timeout is still applicable). For single port configurations, the aging counters are only used when they timeout (become 0) to force read-write direction switching. In this case, external dynamic priority input, arqos (for reads only) can still be used to set the DDRC read priority (2 priority levels: low priority read - LPR, high priority read - HPR) on a command by command basis.

This violation is expected if this value is not programmed to the required SDRAM CKE low time, but memory models should be able to tolerate this violation without malfunction of the model. 0 20 read-write PTR4 PHY Timing Registers 0-4 (PTR0-4) 0x2c 32 0x00000000 0xFFFFFFFF TDINIT3 DRAM Initialization Time 3: DRAM initialization time in DRAM clock cycles corresponding to the following: DDR3 = Time from ZQ initialization command to first command (1 us) Default value corresponds to the DDR3 640ns at 1066 MHz. 18 10 read-write TDINIT2 DRAM Initialization Time 2: DRAM initialization time in DRAM clock cycles corresponding to the following: DDR3 = Reset low time (200 us on power-up or 100 ns after power-up) Default value corresponds to DDR3 200 us at 1066 MHz. 0 18 read-write ACMDLR “AC Master Delay Line Register (ACMDLR)” on page 96 0x30 32 0x00000000 0xFFFFFFFF MDLD MDL Delay: Delay select for the LCDL for the Master Delay Line. 16 8 read-write TPRD Target Period: Target period measured by the master delay line calibration for VT drift compensation.
