RTC0RE: smaRTClock (Real Time Clock) Reset Enable and Flag.
0: Read: Source of last reset was not a smaRTClock alarm or oscillator fail event.
1: Read: Source of last reset was a smaRTClock alarm or oscillator fail event.
FERROR: Flash Error Indicator.
0: Source of last reset was not a Flash read/write/erase error.
1: Source of last reset was a Flash read/write/erase error.
C0RSEF: Comparator0 Reset Enable and Flag.
0: Read: Source of last reset was not Comparator0.
1: Read: Source of last reset was Comparator0.
SWRSF: Software Reset Force and Flag.
0: Read: Source of last reset was not a write to the SWRSF bit.
1: Read: Source of last was a write to the SWRSF bit.
WDTRSF: Watchdog Timer Reset Flag.
0: Source of last reset was not a WDT timeout.
1: Source of last reset was a WDT timeout.
MCDRSF: Missing Clock Detector Flag.
0: Read: Source of last reset was not a Missing Clock Detector timeout.
1: Read: Source of last reset was a Missing Clock Detector timeout.
detected.
PORSF: Power-On Reset Force and Flag.
This bit is set anytime a power-on reset occurs. Writing this bit enables/disables the V
monitor as a reset source. Note: writing ‘1’ to this bit before the V
and stabilized may cause a system reset. See register VDM0CN (SFR Definition 15.1)
0: Read: Last reset was not a power-on or V
1: Read: Last reset was a power-on or V
PINRSF: HW Pin Reset Flag.
0: Source of last reset was not RST pin.
1: Source of last reset was RST pin.
