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 is 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(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

bit 8

CPD: Data Code Protection bit(2)

1 = Data memory code protection is disabled

0 = Data memory code protection is enabled

bit 7

CP: Code Protection bit(3)

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

WPUG5 bit.

bit 5

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.

The entire data EEPROM will be erased when the code protection is turned off during

The entire program memory will be erased when the code protection is turned off.
