CP1:CP0: FLASH Program Memory Code Protection bits(2)
11
= Code protection off
10
= Not supported
01
= Not supported
00
= Code protection on
bit 11
DEBUG: In-Circuit Debugger Mode
1
= In-Circuit Debugger disabled, RB6 and RB7 are general purpose I/O pins
0
= In-Circuit Debugger enabled, RB6 and RB7 are dedicated to the debugger
bit 10
Unimplemented: Read as ‘1’
bit 9
WRT: FLASH Program Memory Write Enable
1
= Unprotected program memory may be written to by EECON control
0
= Unprotected program memory may not be written to by EECON control
bit 8
CPD: Data EE Memory Code Protection
1
= Code protection off
0
= Data EEPROM memory code protected
bit 7
LVP: Low Voltage In-Circuit Serial Programming Enable bit
1
= RB3/PGM pin has PGM function, low voltage programming enabled
0
= RB3 is digital I/O, HV on MCLR must be used for programming
bit 6
BOREN: Brown-out Reset Enable bit(3)
1
= BOR enabled
0
= BOR disabled
bit 3
PWRTEN: Power-up Timer Enable bit(3)
1
= PWRT disabled
0
= PWRT enabled
bit 2
WDTEN: Watchdog Timer Enable bit
1
= WDT enabled
0
= WDT disabled
bit 1-0
FOSC1:FOSC0: Oscillator Selection bits
11
= RC oscillator
10
= HS oscillator
01
= XT oscillator
00
= LP oscillator
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
Note 1: The erased (unprogrammed) value of the configuration word is 3FFFh.
2: All of the CP1:CP0 pairs have to be given the same value to enable the code protection scheme listed.
3: Enabling Brown-out Reset automatically enables Power-up Timer (PWRT), regardless of the value of bit
PWRTEN. Ensure the Power-up Timer is enabled any time Brown-out Reset is enabled.
