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.
