bit 7 bit 0
Legend:
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
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
Address Pointer caused a Reset
0 = An illegal opcode or uninitialized W Reset has not occurred
bit 13-9 Unimplemented: Read as ‘0’
bit 8 VREGS: Voltage Regulator Standby During Sleep bit
(3)
1 = Voltage Regulator is active during Sleep mode
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
bit 6 SWR: Software Reset (Instruction) Flag bit
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
bit 4 WDTO: Watchdog Timer Time-out Flag bit
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
bit 2 IDLE: Wake-up from Idle Flag bit
1 = Device was in Idle mode
0 = Device was not in Idle mode
bit 1 BOR: Brown-out Reset Flag bit
1 = A Brown-out Reset has occurred
0 = A Brown-out Reset has not occurred
Note 1: All of the Reset status bits may 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.
3: For dsPIC33FJ256GPX06A/X08A/X10A devices, this bit is unimplemented and reads back programmed
value.
