KL17 micro - 32 pins. SPI1_PCS shares the same pin as FlexIO_D4. I need to use SPI1 in slave mode AND I need FlexIO_D4. The User's manual on the KL17 series states that if SPI1 is set to be a SLAVE, then the SS pin (SPI1_PCS0) is automatically set to perform the chip select function. BUT I don't want that pin as a chip select, I want it as FlexIO_D4. If I set the PCM Alt value for that pin to FLEXIO_D4 -- will that over-ride the SPI1 Slave mode use for the pin?
Thanks for any comments.
