S32K314 manual chip select

[abhijith_r]

Hi,

I am using S32K314 and in my project I'm using QuadSPI which has dual die stack. In my spi flash there are two chip select for two dies. In the example project the CS pin is controlled by driver code I guess. But I want to assign two pins as CS and controll manually. How can I do it?

In case of CS controlling automatically can I reassign the CS pin while running the program?

Do I understand you correctly you have two possible versions of user board with two memory alternatives or you need to access both memories at a time?

QuadSPI module on this device has only 1 CS line. If you are not using both memories at a time, you could connect CS line to both footprints. If you plan to have both memories at a time and you need to access both independently (you would normally use two CD lines), you could use external switch device and route CS line to first or second memory with using of certain GPIO line as control signal.
