    Question:

    Is it possible to use the chip select pin as a port function when multi-function serial is set to Clock Synchronous Serial Interface (CSIO) mode operation in S6J3110/3120/3200/3300/3350/3360/3370/3400/3510 MCUs?

     

    Answer:

    Yes, set the Port Output Function Selection bit (POF) of the Port Setting Register (PPCPCFGR) as a port function for the chip select pin. You can use a chip select pin as a port function and allow the other serial peripheral interface (SPI) pins (SIN/SOUT/SCK) to operate as SPI functions.
