Legend:
R = Readable bit
P = Programmable bit
U = Unimplemented bit, read as ‘1’
‘0’ = Bit is cleared
‘1’ = Bit is set
-n = Value when blank or after Bulk Erase
bit 13
FCMEN: Fail-Safe Clock Monitor Enable bit
1 = Fail-Safe Clock Monitor and internal/external switchover are both enabled.
0 = Fail-Safe Clock Monitor is disabled
bit 12
IESO: Internal External Switchover bit
1 = Internal/External Switchover mode is enabled
0 = Internal/External Switchover mode is disabled
bit 11
CLKOUTEN: Clock Out Enable bit
If FOSC configuration bits are set to LP, XT, HS modes:
This bit is ignored, CLKOUT function is disabled. Oscillator function on the CLKOUT pin.
All other FOSC modes:
1 = CLKOUT function is disabled. I/O function on the CLKOUT pin.
0 = CLKOUT function is enabled on the CLKOUT pin
bit 10-9
BOREN<1:0>: Brown-out Reset Enable bits
11 = BOR enabled
10 = BOR enabled during operation and disabled in Sleep
01 = BOR controlled by SBOREN bit of the BORCON register
00 = BOR disabled
bit 8
CPD: Data Code Protection bit(1)
1 = Data memory code protection is disabled
0 = Data memory code protection is enabled
bit 7
CP: Code Protection bit
1 = Program memory code protection is disabled
0 = Program memory code protection is enabled
bit 6
MCLRE: MCLR/VPP Pin Function Select bit
If LVP bit = 1:
This bit is ignored.
If LVP bit = 0:
1 =MCLR/VPP pin function is MCLR; Weak pull-up enabled.
0 =MCLR/VPP pin function is digital input; MCLR internally disabled; Weak pull-up under control of
WPUE3 bit.
bit 5
PWRTE: Power-up Timer Enable bit
1 = PWRT disabled
0 = PWRT enabled
bit 4-3
WDTE<1:0>: Watchdog Timer Enable bit
11 = WDT enabled
10 = WDT enabled while running and disabled in Sleep
01 = WDT controlled by the SWDTEN bit in the WDTCON register
00 = WDT disabled
