Reset or Stop Mode Recovery Event
Power-on reset
Reset using RESET pin assertion
Reset using Watchdog Timer time-out
Reset using the On-Chip Debugger (OCTCTL[1] set to 1)
Reset from STOP mode using DBG pin driven Low
Stop Mode Recovery using GPIO pin transition
Stop Mode Recovery using WDT time-out
POR—Power-On Reset indicator
This bit is set to 1 if a Power-On Reset event occurs and is reset to 0, if a WDT time-out or
Stop Mode Recovery occurs. Reading this register also reset this bit to 0.
STOP—Stop Mode Recovery indicator
This bit is set to 1 if a Stop Mode Recovery occurs. If the STOP and WDT bits are both set
to 1, the Stop Mode Recovery occurs because of a WDT time-out. If the STOP bit is 1 and
the WDT bit is 0, the Stop Mode Recovery is not caused by a WDT time-out. This bit is
reset by a Power-on reset or a WDT time-out that occurred while not in STOP mode.
Reading this register also resets this bit.
WDT—Watchdog Timer time-out indicator
This bit is set to 1 if a WDT time-out occurs. A Power-On Reset resets this pin. A Stop
Mode Recovery from a change in an input pin also resets this bit. Reading this register
resets this bit. This read must occur before clearing the WDT interrupt.
EXT—External reset indicator
If this bit is set to 1, a reset initiated by the external RESET pin occurred. A Power-On
Reset or a Stop Mode Recovery from a change in an input pin resets this bit. Reading this
register resets this bit.
Reserved—Must be 0.
