 *  @defgroup MIBSPI MIBSPI
 *  @brief Multi-Buffered Serial Peripheral Interface Module.
 *  
 *  The MibSPI/MibSPIP is a high-speed synchronous serial input/output port that allows a serial bit stream of
 *  programmed length (2 to 16 bits) to be shifted in and out of the device at a programmed bit-transfer rate.
 *  The MibSPI has a programmable buffer memory that enables programmed transmission to be completed
 *  without CPU intervention
