Legend:
R = Readable bit
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15
TRAPR: Trap Reset Flag bit
1 = A Trap Conflict Reset has occurred
0 = A Trap Conflict Reset has not occurred
1 = A Trap Conflict Reset has occurred
0 = A Trap Conflict Reset has not occurred
bit 14
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
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
bit 13-10
Unimplemented: Read as ‘0’
bit 9
CM: Configuration Mismatch Flag bit
1 = A Configuration Mismatch Reset has occurred
0 = A Configuration Mismatch Reset has NOT occurred
1 = A Configuration Mismatch Reset has occurred
0 = A Configuration Mismatch Reset has NOT occurred
bit 8
VREGS: Voltage Regulator Standby During Sleep bit
1 = Voltage regulator is active during Sleep
0 = Voltage regulator goes into Standby mode during Sleep
1 = Voltage regulator is active during Sleep
0 = Voltage regulator goes into Standby mode during Sleep
bit 7
EXTR: External Reset (MCLR) Pin bit
1 = A Master Clear (pin) Reset has occurred
0 = A Master Clear (pin) Reset has not occurred
1 = A Master Clear (pin) Reset has occurred
0 = A Master Clear (pin) Reset has not occurred
bit 6
SWR: Software Reset (Instruction) Flag bit
1 = A RESET instruction has been executed
0 = A RESET instruction has not been executed
1 = A RESET instruction has been executed
0 = A RESET instruction has not been executed
bit 5
SWDTEN: Software Enable/Disable of WDT bit
(2)
1 = WDT is enabled
0 = WDT is disabled
0 = WDT is disabled
bit 4
WDTO: Watchdog Timer Time-out Flag bit
1 = WDT time-out has occurred
0 = WDT time-out has not occurred
1 = WDT time-out has occurred
0 = WDT time-out has not occurred
bit 3
SLEEP: Wake-up from Sleep Flag bit
1 = Device has been in Sleep mode
0 = Device has not been in Sleep mode
1 = Device has been in Sleep mode
0 = Device has not been in Sleep mode
Note 1: 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.
2: If the FWDTEN Configuration bit is ‘1’ (unprogrammed), the WDT is always enabled, regardless of the
SWDTEN bit setting.
