Hi
I am using nrs5340 chip as an SOC in my project. I want to use some Port1 Pins in my hardware design. As far as I studied in your Dev Zone, this
is inactive by default in nrf5340. I have seen some similar questions in the Dev Zone but I couldn't understand clearly how it could be activated.
I have written a very simple program and tried to toggle for example to toggle P1.01 in my code.
My code is attached below.
I would be very thankful if you could help me in this regard.
Best regards
