Code protection for 2K program memory
11
= Program memory code protection off
10
= 0400h-07FFh code protected
01
= 0200h-07FFh code protected
00
= 0000h-07FFhcode protected
Code protection for 1K program memory
11
= Program memory code protection off

Data Code Protection bit
(3)
1
= Data memory code protection off
0
= Data memory code protected
bit 7:
LVP
: Low Voltage Programming Enable
1
= RB4/PGM pin has PGM function, low voltage programming enabled
0
= RB4/PGM is digital I/O, HV on MCLR must be used for programming
BODEN
: Brown-out Detect Reset Enable bit
(1)
1
= BOD Reset enabled
0
= BOD Reset disabled
bit 6:
bit 5:
MCLRE
: RA5/MCLR pin function select
1
= RA5/MCLR pin function is MCLR
0
= RA5/MCLR pin function is digital Input, MCLR internally tied to V
DD
PWRTEN
: Power-up Timer Enable bit
(1)
1
= PWRT disabled
0
= PWRT enabled
bit 3:
bit 2:
WDTEN
: Watchdog Timer Enable bit
1
= WDT enabled
0
= WDT disabled
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
bit 4, 1-0:
Note
1:
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.
