This is regarding S32K Pin Configuration and I am using S32K146.


When we select Pin Function as a GPIO Pin we also selct Pin Direction.

So would like to ask for

1. All kind of Pin function we need to config Pin input or Output direction? e.g. In case of SPI 'MOSI' Pin Function sets by defalut as 'Out'? Or we need to set it.

2. SPI CLK needs to be configure as 'Output'?

3.In case of SPI can we use any GPIO as a slave select Pin or we need to use Pin function 'LPSPI1_PCS3' to select slave

4. Can someone put some light on Pin function as FTM? and when can we use FTM Pin Function? Can we use this to supply voltage to any other peripherals Or to read supply voltage of other peripheral Or to get supply voltage form other Peripheral?


Thanks for your support in advance.
