I'm learing stm32 spi,

In normal way of master mode, 

I have to low the slave select pin, then transmit data, then high the slave select pin

I know that I can use dma to transmit data,

but I am not sure that dma can control slave select pin or not?

 

Can I have anyway to to whole transmit data(including control slave select pin) using all hardware?
