Enumeration Type Documentation

◆ nrfx_reset_reason_mask_t

enum nrfx_reset_reason_mask_t

Reset reason bit masks.

Enumerator
NRFX_RESET_REASON_RESETPIN_MASK	Reset from pin-reset detected. Reset from watchdog/application watchdog timer 0 detected.
NRFX_RESET_REASON_DOG0_MASK	Reset from watchdog/application watchdog timer 0 detected.
NRFX_RESET_REASON_DOG_MASK	Reset from application CTRL-AP detected.
NRFX_RESET_REASON_CTRLAP_MASK	Reset from soft reset/application soft reset detected. Deprecated.
NRFX_RESETREAS_SREQ_MASK	Reset from soft reset/application soft reset detected.
NRFX_RESET_REASON_SREQ_MASK	Reset from CPU lockup/application CPU lockup detected.
NRFX_RESET_REASON_LOCKUP_MASK	Reset due to wakeup from System OFF mode when wakeup is triggered by DETECT signal from GPIO.
NRFX_RESET_REASON_OFF_MASK	Reset due to wakeup from System OFF mode when wakeup is triggered by ANADETECT signal from LPCOMP.
NRFX_RESET_REASON_LPCOMP_MASK	Reset due to wakeup from System OFF mode when wakeup is triggered by entering the debug interface mode.
NRFX_RESET_REASON_DIF_MASK	Reset from network soft reset detected.
NRFX_RESET_REASON_LSREQ_MASK	Reset from network CPU lockup detected.
NRFX_RESET_REASON_LLOCKUP_MASK	Reset from network watchdog timer detected.
NRFX_RESET_REASON_LDOG_MASK	Force off reset from application core detected.
NRFX_RESET_REASON_NFC_MASK	Reset after wakeup from System OFF mode due to NFC field being detected. Reset from application watchdog timer 1 detected.
NRFX_RESET_REASON_DOG1_MASK	Reset after wakeup from System OFF mode due to VBUS rising into valid range.
NRFX_RESET_REASON_VBUS_MASK	Reset from network CTRL-AP detected.
NRFX_RESET_REASON_CTRLAPHARD_MASK	Reset due to CTRL-AP hard reset. Reset due to CTRL-AP pin reset.
NRFX_RESET_REASON_CTRLAPPIN_MASK	Reset due to wakeup from GRTC.
NRFX_RESET_REASON_GRTC_MASK	Reset due to illegal tampering of the device.

Function Documentation

◆ nrfx_reset_reason_clear()

__STATIC_INLINE void nrfx_reset_reason_clear ( uint32_t mask )

Function for clearing the selected reset reason fields.

Parameters

[in] mask Mask constructed from nrfx_reset_reason_mask_t values.

◆ nrfx_reset_reason_get()

__STATIC_INLINE uint32_t nrfx_reset_reason_get ( void )

Function for getting the reset reason bitmask.

Unless cleared, the RESETREAS register is cumulative. If none of the reset sources is flagged, the chip was reset from the on-chip reset generator. This indicates a power-on-reset or a brown out reset.

Returns: Mask of reset reasons constructed from nrfx_reset_reason_mask_t values.
