POR—Power-On Reset indicator
This bit is set to 1 if a POR event occurs and is reset to 0, if a WDT time-out or Stop Mode
Recovery occurs. Reading this register also resets 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 POR 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 POR 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 POR 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.
