nRf5340 Port 1 pin restricted to 12

[AmalSurendran]

I am using the nRF5340 in our project. I am using both ports completely and I was unable to use the GPIOs after P1.11. When I debugged the issue I found that the GPIOs are limited to 12 on P1 in the header file. May I know if there is any particular reason for this?

Hi,

You are right that P1_PIN_NUM is defined to 12 in both nrf5340_network_peripherals.h and nrf5340_application_peripherals.h. I suspect it is a bug and that it should have been 16, but I will verify and get back to you.

Update: This is a confirmed bug. P1_PIN_NUM should be set to 16.
