Hi,
We are using LS1043A, We are connecting two SPI slaves(CS0, CS1) to LS1043A(Master). Shall i use the other two chip selects (CS2, CS3) pins as GPIO? is that possible?
Please confirm.
Thanks.
Have a great day,
The RCW[SPI_BASE] configures functionality of all SPI_CS_Bn pins. So if you need for any of SPI_CS_B[0:3] chip select signal all 4 pins will be configured as SPI_CS_B[0:3] and cannot be used as GPIO.

Hi,
Thanks for your reply,
Earlier i have listed down all the pins in LS1043A for Muxed Signal Selection and raised a query to check whether Mux Signal selection is correct or not. I have attached that query link below.
Kindly update me the above query
The SPI_CS[] and GPIO are mutually exclusive as you can see in the LS1043A reference manual
