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
RETEN: Retention Sleep Mode⁽³⁾
1 = Regulated voltage supply provided by the Retention Regulator (RETREG) during Sleep
0 = Regulated voltage supply provided by the main Voltage Regulator (VREG) during Sleep
Unimplemented: Read as ‘0’
CM: Configuration Word Mismatch Reset Flag bit
1 = A Configuration Word Mismatch Reset has occurred
0 = A Configuration Word Mismatch Reset has not occurred
PMSLP: Program Memory Power During Sleep bit
1 = Program memory bias voltage remains powered during Sleep
0 = Program memory bias voltage is powered down during Sleep and the voltage regulator enters
Standby mode
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
Note 1:
2:
3:
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.
If the FWDTENx Configuration bit is ‘1’ (unprogrammed), the WDT is always enabled regardless of the
SWDTEN bit setting.
This is implemented on PIC24FV16KMXXX parts only; not used on PIC24F16KMXXX devices.
