SPI TX FIFO?

Other Parts Discussed in Thread: TMS570LS0232

Hello,

Is there a TXBUF FIFO for SPI on TMS570LS02xx (for non mibSPI)? Also, is DMA supported? 

Thanks!

    There is a single TX buffer before the shift register on the standard SPI. The first word to transmit will move quickly from the TXBUF to the shift register. The software can then quickly write the second word to transmit. It will be held in the TXBUF until the TX shift register is empty. There is no DMA on the TMS570LS0232.
