NFC Usage as GPIO Pins

Hi all,

I am trying to configure the NFC Pins for usage in an SPI application. However they do not even work for a simple nrf_gpio_pin_set after configuring them with nrf_gpio_cfg_output . Every other Pin seems to work, though.

After some reading in this forum I found that those Pins should be configured as GPIO first by setting the UICR-Register to 0xFFFFFFFE instead of 0xFFFFFFFF. I did define CONFIG_NFCT_PINS_AS_GPIOS and verified that the value of register 0x1000120C is 0xFFFFFFFE. So far it all seems to be correct.

Sill, I do not get those Pins to do anything. Is there anything I missed, in those various Forum Threads? Are more configurations to be made first?

Thanks for any help in advance! Cheers
