| help |
| Two pins are usually reserved for NFC in SoCs that implement the |
| NFCT peripheral. This option switches them to normal GPIO mode. |
| HW enabling happens once in the device lifetime, during the first |
| system startup. Disabling this option will not switch back these |
| pins to NFCT mode. Doing this requires UICR erase prior to |
| flashing device using the image which has this option disabled. |
