TRAPR: Trap Reset Flag bit
1 = A Trap Conflict Reset has occurred
0 = A Trap Conflict Reset has not occurred
IOPUWR: Illegal Opcode or Uninitialized W Access Reset Flag bit
1 = An illegal opcode detection, an illegal address mode or uninitialized W register used as an
Address Pointer caused a Reset
0 = An illegal opcode or uninitialized W Reset has not occurred
Unimplemented: Read as ‘0’
CM: Configuration Mismatch Flag bit
1 = A configuration mismatch Reset has occurred
0 = A configuration mismatch Reset has NOT occurred
VREGS: Voltage Regulator Standby During Sleep bit
1 = Voltage regulator is active during Sleep
0 = Voltage regulator goes into Standby mode during Sleep
EXTR: External Reset (MCLR) Pin bit
1 = A Master Clear (pin) Reset has occurred
0 = A Master Clear (pin) Reset has not occurred
SWR: Software Reset (Instruction) Flag bit
1 = A RESET instruction has been executed
0 = A RESET instruction has not been executed
SWDTEN: Software Enable/Disable of WDT bit⁽²⁾
1 = WDT is enabled
0 = WDT is disabled
WDTO: Watchdog Timer Time-out Flag bit
1 = WDT time-out has occurred
0 = WDT time-out has not occurred
SLEEP: Wake-up from Sleep Flag bit
1 = Device has been in Sleep mode
0 = Device has not been in Sleep mode
IDLE: Wake-up from Idle Flag bit
1 = Device was in Idle mode
0 = Device was not in Idle mode
Note 1:
2:
All of the Reset status bits can be set or cleared in software. Setting one of these bits in software does not
cause a device Reset.
If the FWDTEN Configuration bit is ‘1’ (unprogrammed), the WDT is always enabled, regardless of the
SWDTEN bit setting.
