CONFIG_NFCT_PINS_AS_GPIOS¶
NFCT pins as GPIOs
Type: bool
Help¶
P0.9 and P0.10 are usually reserved for NFC. This option switch 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.
Direct dependencies¶
(SOC_NRF52832 || SOC_NRF52840) && SOC_FAMILY_NRF
(Includes any dependencies from if’s and menus.)
Defaults¶
No defaults. Implicitly defaults to n.
