TMS320F28386D: SPI: Only start transmission after FIFO loading

Part Number: TMS320F28386D


I have a particular use case where I want to be sure the FIFO is fully loaded before I start the exchange with the slave (CPU is MASTER).

The reason is, as the peripheral frame is shared with the DMA, I have to ensure the words are in the FIFO to be sure I respect the protocol awaited by that salve.

Is there a way to achieve that ?

I have the feeling, from the registers fields descriptions, that this is not something feasible.

Best regards,
