bit 7

bit 0

bit 7

IPEN: Interrupt Priority Enable bit

= Enable priority levels on interrupts

= Disable priority levels on interrupts (PIC16CXXX Compatibility mode)

bit 6

SBOREN: BOR Software Enable bit

If BOREN1:BOREN0 = 01:

= BOR is enabled

= BOR is disabled

If BOREN1:BOREN0 = 00, 10 or 11:

Bit is disabled and read as ‘0’.

Note 1: If SBOREN is enabled, its Reset state is ‘1’; otherwise, it is ‘0’.

bit 5

Unimplemented: Read as ‘0’

bit 4

RI: RESET Instruction Flag bit

= The RESET instruction was not executed (set by firmware only)

= The RESET instruction was executed causing a device Reset (must be set in software after

a Brown-out Reset occurs)

bit 3

TO: Watchdog Timer Time-out Flag bit

= Set by power-up, CLRWDT instruction or SLEEP instruction

= A WDT time-out occurred

bit 2

PD: Power-Down Detection Flag bit

= Set by power-up or by the CLRWDT instruction

= Set by execution of the SLEEP instruction

bit 1

POR: Power-on Reset Status bit

= A Power-on Reset has not occurred (set by firmware only)

= A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)

bit 0

BOR: Brown-out Reset Status bit

= A Brown-out Reset has not occurred (set by firmware only)

= A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)

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

Note 1: It is recommended that the POR bit be set after a Power-on Reset has been

detected, so that subsequent Power-on Resets may be detected.

2: Brown-out Reset is said to have occurred when BOR is ‘0’ and POR is ‘1’ (assuming

that POR was set to ‘1’ by software immediately after POR).
