bit 13

bit 0

bit 13-10:

CP1:CP0: Code Protection bits (2)

Code protection for 2K program memory

= Program memory code protection off

= 0400h-07FFh code protected

= 0200h-07FFh code protected

= 0000h-07FFhcode protected

Code protection for 1K program memory

= Program memory code protection off

= 0200h-03FFh code protected

= 0000h-03FFh code protected

bit 9:

Unimplemented: Read as ‘0’

bit 8:

CPD: Data Code Protection bit(3)

= Data memory code protection off

= Data memory code protected

bit 7:

LVP: Low Voltage Programming Enable

= RB4/PGM pin has PGM function, low voltage programming enabled

= RB4/PGM is digital I/O, HV on MCLR must be used for programming

bit 6:

BODEN: Brown-out Detect Reset Enable bit (1)

= BOD Reset enabled

= BOD Reset disabled

bit 5:

MCLRE: RA5/MCLR pin function select

= RA5/MCLR pin function is MCLR

= RA5/MCLR pin function is digital Input, MCLR internally tied to V

bit 3:

PWRTEN: Power-up Timer Enable bit (1)

= PWRT disabled

= PWRT enabled

bit 2:

WDTEN: Watchdog Timer Enable bit

= WDT enabled

= WDT disabled

bit 4, 1-0:

FOSC2:FOSC0: Oscillator Selection bits(4)

111

= ER oscillator: CLKOUT function on RA6/OSC2/CLKOUT pin, Resistor on RA7/OSC1/CLKIN

110

= ER oscillator: I/O function on RA6/OSC2/CLKOUT pin, Resistor on RA7/OSC1/CLKIN

101

= INTRC oscillator: CLKOUT function on RA6/OSC2/CLKOUT pin, I/O function on RA7/OSC1/CLKIN

100

= INTRC oscillator: I/O function on RA6/OSC2/CLKOUT pin, I/O function on RA7/OSC1/CLKIN

011

= EC: I/O function on RA6/OSC2/CLKOUT pin, CLKIN on RA7/OSC1/CLKIN

010

= HS oscillator: High speed crystal/resonator on RA6/OSC2/CLKOUT and RA7/OSC1/CLKIN

001

= XT oscillator: Crystal/resonator on RA6/OSC2/CLKOUT and RA7/OSC1/CLKIN

000

= LP oscillator: Low power crystal on RA6/OSC2/CLKOUT and RA7/OSC1/CLKIN

Note

Enabling Brown-out Detect Reset automatically enables Power-up Timer (PWRT) regardless of the value of bit PWRTE.

Ensure the Power-up Timer is enabled anytime Brown-out Detect Reset is enabled.

All of the CP1:CP0 pairs have to be given the same value to enable the code protection scheme listed.

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

When MCLR is asserted in INTRC or ER mode, the internal clock oscillator is disabled.

Legend

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

1 = bit is set

0 = bit is cleared

x = bit is unknown
