Legend:

C = Clearable bit

HS = Hardware Settable 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

= A Trap Conflict Reset has occurred

= A Trap Conflict Reset has not occurred

bit 14

IOPUWR:

Illegal Opcode or Uninitialized W Access Reset Flag bit

= An illegal opcode detection, an illegal address mode or uninitialized W register used as an

Address Pointer caused a Reset

= An illegal opcode or uninitialized W Reset has not occurred

bit 13

SBOREN:

Software Enable/Disable of BOR bit

= BOR is turned on in software

= BOR is turned off in software

bit 12-11

Unimplemented:

Read as ‘0’

bit 10

DPSLP:

Deep Sleep Mode Flag bit

= Deep Sleep has occurred

= Deep Sleep has not occurred

bit 9

Unimplemented:

Read as ‘0’

bit 8

PMSLP:

Program Memory Power During Sleep bit

= Program memory bias voltage remains powered during Sleep

= Program memory bias voltage is powered down during Sleep

bit 7

EXTR:

External Reset (MCLR) Pin bit

= A Master Clear (pin) Reset has occurred

= A Master Clear (pin) Reset has not occurred

bit 6

SWR:

Software Reset (Instruction) Flag bit

= A RESET instruction has been executed

= A RESET instruction has not been executed

bit 5

SWDTEN:

Software Enable/Disable of WDT bit(2)

= WDT is enabled

= WDT is disabled

bit 4

WDTO:

Watchdog Timer Time-out Flag bit

= WDT time-out has occurred

= WDT time-out has not occurred

bit 3

SLEEP:

Wake-up from Sleep Flag bit

= Device has been in Sleep mode

= Device has not been in Sleep mode

bit 2

IDLE:

Wake-up from Idle Flag bit

= Device has been in Idle mode

= Device has not been in Idle mode

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.

If the FWDTEN Configuration bit is ‘1’ (unprogrammed), the WDT is always enabled, regardless of the

SWDTEN bit setting.
