Thank you so much! Was trying to use those two pins as an output and thought it was something with my custom board. Took me a bit to figure out it was related to the NFC.

Hi Bob

You are correct, there is some additional settings to be aware of when configuring the NFC pins as GPIOs. This depends on the IDE you are using. If using Keil μvision, please refer to this post. If using SEGGER Embedded Studio this picture should explain how to configure your NFC pins as GPIOs:

If you are using another IDE, please specify which one and I will find out how to do this in that one.

Best regards,

Simon
