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
SBOREN: Software Enable/Disable of BOR bit
1 = BOR is turned on in software
0 = BOR is turned off in software
Unimplemented: Read as ‘0’
DPSLP: Deep Sleep Mode Flag bit
1 = Deep Sleep has occurred
0 = Deep Sleep has not occurred
Unimplemented: Read as ‘0’
PMSLP: Program Memory Power During Sleep/Idle bit
1 = Program memory bias voltage remains powered during Sleep/Idle
0 = Program memory bias voltage is powered down during Sleep/Idle
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 has been in Idle mode
0 = Device has not been in Idle mode
BOR: Brown-out Reset Flag bit
1 = A Brown-out Reset has occurred (the BOR is also set after a POR)
