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
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
Unimplemented: Read as ‘1’
CP: Code Protection bit⁽²⁾
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
WPUE3 bit.
PWRTE: Power-Up Timer Enable bit
1 = PWRT disabled
0 = PWRT enabled
WDTE<1:0>: Watchdog Timer Enable bits
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
FOSC<2:0>: Oscillator Selection bits
111 = ECH:External clock, High-Power mode: on CLKIN pin
110 = ECM: External clock, Medium-Power mode: on CLKIN pin
101 = ECL: External clock, Low-Power mode: on CLKIN pin
100 = INTOSC oscillator: I/O function on CLKIN pin
011 = EXTRC oscillator: External RC circuit connected to CLKIN pin
010 = HS oscillator: High-speed crystal/resonator connected between OSC1 and OSC2 pins
001 = XT oscillator: Crystal/resonator connected between OSC1 and OSC2 pins
000 = LP oscillator: Low-power crystal connected between OSC1 and OSC2 pins
Note 1: Enabling Brown-out Reset does not automatically enable Power-up Timer.
2: Once enabled, code-protect can only be disabled by bulk erasing the device.
