I used S32k144 chip and used S32 design studio IDE. I tried to configure portA and portc's pin out. found that portc c can be controlled by code. but port A pin did not work.  I debugged it, found that Port A PDOR is updated by code, but the real pin output status did not get change. so I want to check port A pin control register. but I did not know the port A pin control register base address. do you know what's the problem for port A did not work issue. and what 's the base address of port A pin control register?

Hi,

Which Port A pin do you mean?

Can you share the Port A configuration code.

Memory map is attached to the RM:

S32K1xx_Memory_map.xlsx 

Port A 0x40049000 - 0x40049FFF.

But you can see Pin Control Registers in the S32DS.

daniel,

got you。curently,all port A pins lost function while port B/C/D/E pins worked well。maybe port A is damaged。 but sadly,now I only had one pcb board。will get another board next week to verify。

Anyway,thank you very much!
