	help
	  Hidden function to indicate that that the soc_secure functions are
	  available.
	  The functions are always available when not in non-secure.
	  For non-secure the functions must redirect to secure services exposed
	  by the secure firmware.

	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.

	  NFC pins in nRF52 series: P0.09 and P0.10
	  NFC pins in nRF5340: P0.02 and P0.03

config NRF_APPROTECT_USE_UICR
	bool "Use UICR"
	help
	  When this option is selected, the SystemInit() function loads the
	  firmware branch state of the APPROTECT mechanism from UICR, so if
	  UICR->APPROTECT is disabled, CTRLAP->APPROTECT will be disabled.

config NRF_APPROTECT_LOCK
	bool "Lock"

	  When this option is selected, the SystemInit() function locks
	  the firmware branch of the APPROTECT mechanism, preventing it
	  from being opened.

	bool "Allow user handling"
	depends on !SOC_SERIES_NRF52X
	help
	  When this option is selected, the SystemInit() function does not
	  touch the APPROTECT mechanism, allowing the user code to handle it
	  at later stages, for example, to implement authenticated debug.
