TMS320F28069: SPI DMA Support

Joseph Griffin
Prodigy 10 points
Part Number: TMS320F28069


Tool/software:

Does the TMS320F28069 support triggering a DMA burst upon the SPI RX FIFO filling? In the TRM, section 12.2.4 "DMA Support" suggests that it is possible, but PERINTSEL within the DMA MODE register doesn't seem to support any SPI triggers. Was the "DMA Support" section just accidentally copied over from a different TRM?

    Hi Joesph,

    You are correct - SPI DMA is not support on this device. The SPI module is not listed in the DMA chapter as a trigger source for the DMA. It seems this section snuck into the F2806x TRM. I will file a bug to remove it. Thank you!

    Best Regards,

    Allison
