◆ DMA_Initialize()

void DMA_Initialize ( void  )

Enables the DMA module.

This function enables the DMA streams.

Use Tx interrupt to transfer last word with CSHOLD = 0 DO NOT ACTIVATE FOR SLAVE SPI NODES (here SPI4 used as slave)

◆ dmaGroupANotification()

void UNIT_TEST_WEAK_IMPL dmaGroupANotification ( dmaInterrupt_t  inttype,
uint32  channel 
)

Function called on DMA complete interrupts (TX and RX). Defined as weak in HAL.

TX SPI DMA interrupt: last but one word transmitted, last word is transmitted manually (in order to write CSHOLD field)

SPI configured as slave
