AM6442: MCSPI chip select using GPIO

Part Number: AM6442


Hi TI,

In AM6442 each MCSPI has 4 CS pins but for our requirement we need atleast 5 CS pins for each MCSPI for our design.

Is there any possibility to increase the CS pins using GPIO'S. If yes what extra configuration need to be done on the software to make the processor understand we are controlling CS using GPIO ?

And also is there any impact if we use GPIO to control the CS pins ?
