CONFIG_NFCT_PINS_AS_GPIOS

NFCT pins as GPIOs

NFCT pins as GPIOs

Type: bool

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.
