    Hello,

    In Multi-buffer mode the transmit data has to be written to the TXRAM locations and the receive data has to be read from RXRAM locations of the multi-buffer
    RAM. The SPIDAT0 and SPIDAT1 are not used in MibSPI mode.

    If you want to use SPIDAT0/1, please use SPI compatibility mode instead.
