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 7
IPEN:
Interrupt Priority Enable bit
1
= Enable priority levels on interrupts
0
= Disable priority levels on interrupts (PIC16CXXX Compatibility mode)
bit 6
SBOREN:
BOR Software Enable bit
If BOREN<1:0> = 01:
1
= BOR is enabled
0
= BOR is disabled
If BOREN<1:0> = 00, 10 or 11:
Bit is disabled and read as ‘0’.
bit 5
CM:
Configuration Mismatch Flag bit
1
= A Configuration Mismatch Reset has not occurred
0
= A Configuration Mismatch Reset has occurred (must be set in software after a Configuration
Mismatch Reset occurs)
bit 4
RI: RESET
Instruction Flag bit
1
= The RESET instruction was not executed (set by firmware only)
0
= The RESET instruction was executed causing a device Reset (must be set in software after a
Brown-out Reset occurs)
bit 3
TO:
Watchdog Time-out Flag bit
1
= Set by power-up, CLRWDT instruction or SLEEP instruction
0
= A WDT time-out occurred
bit 2
PD:
Power-Down Detection Flag bit
1
= Set by power-up or by the CLRWDT instruction
0
= Set by execution of the SLEEP instruction
bit 1
POR:
Power-on Reset Status bit
1
= A Power-on Reset has not occurred (set by firmware only)
0
= A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)
bit 0
BOR:
Brown-out Reset Status bit
1
= A Brown-out Reset has not occurred (set by firmware only)
0
= A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)
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 a Power-on Reset).
