First Im the student first starting studying with NXP boards.
The problem I have is that I have no idea how to implement a 4x4 matrix keypad in s32k144.
where Can I find some 'membrane keypad' example project for s32k144?
Thx 4 helping

Please download S32K1xx MCU Family - Reference Manual and then you can see the PORT and GPIO registers.
Hi
Sorry we don't have example project with membrane keypad.
But I think you can use PORT interrupt to check which pin has be pressed.
You can refer the Button interrupt in can_pal_s32k144 of SDK.
Best Regards,
Robin

Additionally, I was using Atmel's AVR before moving on.
Is there any register related to port input and output such as DDRA, PORTA, PINA, etc. similar to AVR in NXP? I want to control multiple inputs and outputs at the same time.
