|
|
* The Universal Serial Bus (USB) module complies with the USB 2.1 specification.
|
|
*
|
|
* The following peripherals are used by this module:
|
|
* - USB (Universal Serial Bus)
|
|
*
|
|
* The following devices can use this module:
|
|
* - Atmel | SMART SAM D21
|
|
* - Atmel | SMART SAM R21
|
|
* - Atmel | SMART SAM D11 (Only USB device support on SAM D11 device)
|
|
* - Atmel | SMART SAM L21
|
|
* - Atmel | SMART SAM L22 (Only USB device support on SAM L22 device)
|
|
* - Atmel | SMART SAM DA1
|
|
*
|
|
* The USB module covers following mode:
|
|
* \if USB_DEVICE_MODE
|
|

|
|
* \if USB_HOST_MODE
|

|
|
* \if USB_HS_MODE
|
|
* - USB High Speed (480Mbit/s)
|
|
* \endif
|
|
* - USB Full Speed (12Mbit/s)

|
|
* - USB Low Speed (1.5Mbit/s)
|

|
|
* The USB module supports Link Power Management (LPM-L1) protocol.

|
|
* USB support needs whole set of enumeration process, to make the device
|
|
* recognizable and usable. The USB driver is designed to interface to the
