bit 7

bit 0

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

= Fail-Safe Clock Monitor is enabled

= Fail-Safe Clock Monitor is disabled

bit 12

IESO:

Internal External Switchover bit

= Internal/External Switchover mode is enabled

= 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:

= CLKOUT function is disabled. I/O function on the CLKOUT pin.

= CLKOUT function is enabled on the CLKOUT pin

bit 10-9

BOREN<1:0>:

Brown-out Reset Enable bits

= BOR enabled

= BOR enabled during operation and disabled in Sleep

= BOR controlled by SBOREN bit of the BORCON register

= BOR disabled

bit 8

Unimplemented:

Read as ‘1’

bit 7

CP:

Code Protection bit

= Program memory code protection is disabled

= 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:

=MCLR/VPP pin function is MCLR; Weak pull-up enabled.

=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

= PWRT disabled

= PWRT enabled

bit 4-3

WDTE<1:0>:

Watchdog Timer Enable bit

= WDT enabled

= WDT enabled while running and disabled in Sleep

= WDT controlled by the SWDTEN bit in the WDTCON register

= WDT disabled
