RM57L843: SPI transfer triggered by timer

Hi,

Here is what I am trying to do, but I am having some difficulties finding all the information.

I want to trigger SPI transfers using a timer. I was thinking of using one of the N2HET timers to trigger the SPI transfer.

I plan on using the SPI in DMA mode, and trigger SPI transfers periodically.

I am assuming that if I configured the corresponding CS pin in functional mode (PC0 register), the CS signal would handled automatically by the SPI peripheral.

Is this even possible?

To understand why I want this, I need to use the ADS7953 for ADC conversions and read back the converted values of multiple channels using the setup. It is configured in manual (single shot) mode, so I need to issue a separate SPI tranfser for each channel that I want to read.

I am assuming that if I configured the corresponding CS pin in functional mode (PC0 register), the CS signal would handled automatically by the SPI peripheral.

Thank you for your help
