Dear experts,
I want to ask for your guidance on TM4C123 SSI in SPI slave mode with DMA enabled. The customer use case is they want to let the CPU know the CS pull low event when the SPI master pull CS signal low to read data from SPI slave, so that in the event/interrupt handler, the customer can add data preparation code, such as reconfiguring DMA, but I can not find any interrupt source for this event, can you help to give some guidance to achieve this goal?
Thanks.
Eric.
