Hello NXP.

Very Good morning.


I am working on a automotive project using MPC5746C MCU. There is a requirement like, I need to read the PORST pin on system power ON and while running in BOOT and main application.


We want to always read the PORST pin and needs to perform some operations in my application.


But, It is not mentioned like a general purpose IO pin. Can you please suggest me a method to read such pins status ?


Expecting an earlier response.
