S32K146 GPIO port has no function when lpit module is running

Hello EveryOne,

I found the GPIO ports have no function when enable the lpit module, then I can not detect the gpio port power level changed and can output power level via gpio output port.

If disable the lpit module, the the gpio ports are work normal.

the code as the follow picture:

Hello Senlent,

I have fixed the problem, the root cause is configure mistake, I updated the configure, the gpio module and lpit module are all ok.

Hi@547416104
