STOP—Stop Mode Recovery Indicator
If this bit is set to 1, a Stop Mode Recovery is occurred. If the STOP and WDT bits are both
set to 1, the Stop Mode Recovery occurred because of a WDT time-out. If the STOP bit is
1 and the WDT bit is 0, the Stop Mode Recovery was 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
If this bit is set to 1, a WDT time-out occurred. 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 Power-On
Reset or a Stop Mode Recovery from a change in an input pin resets this bit. Reading this
register resets this bit.
