Thanks, I found the solution. If it could be useful:

the address of the register is 0x1000120C and the bit is the one with the lowest weight, setting the register at the value 0xFFFFFFFE it works.

Hi, please do you have a code example that works with Segger SES ? I am not able to configure correctly the pin.

Hi DEGHI,

I would recommend that you read this documentation on how to change the NFC pins to GPIOs.

Note that if you use the NFC pins as normal GPIO pins instead, they are limited to lower frequency than other GPIOs.

Also see the documentation on how to use the NFC pins as GPIOs on the 52DK.
