I am working on STM32F7 Micro controller , In that I need SPI interface with more then 16 bit data size . As per SPI device requirement the SPI Chip select needs to be active low for more then 16 bit data size. Presently I am operating CS pin by using GPIO pin. But in this case I can't use DMA .
Is there any possible ways to get more then 16 bit data size.?
I have attached the SPI bus cycle requirement of the device.
