FCMEN: Fail-Safe Clock Monitor Enable bit
1 = Fail-Safe Clock Monitor is enabled
0 = Fail-Safe Clock Monitor is disabled
IESO: Internal External Switchover bit
1 = Internal/External Switchover mode is enabled
0 = Internal/External Switchover mode is disabled
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
BOREN<1:0>: Brown-out Reset Enable bits⁽¹⁾
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
CPD: Data Code Protection bit⁽²⁾
1 = Data memory code protection is disabled
0 = Data memory code protection is enabled
CP: Code Protection bit⁽³⁾
1 = Program memory code protection is disabled
0 = Program memory code protection is enabled
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
WPUG5 bit.
PWRTE: Power-up Timer Enable bit⁽¹⁾
1 = PWRT disabled
0 = PWRT enabled
Note 1: Enabling Brown-out Reset does not automatically enable Power-up Timer.
2: The entire data EEPROM will be erased when the code protection is turned off during
3: The entire program memory will be erased when the code protection is turned off.
