Note 1: The erased (unprogrammed) value of the configuration word is 3FFFh.
CP1
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 PWRTE.
CP0
Ensure the Power-up Timer is enabled any time Brown-out Reset is enabled.
DEBUG
CP1:CP0: FLASH Program Memory Code Protection bits
11 = Code protection off
10 = 1F00h to 1FFFh code protected (PIC16F877, 876)
10 = 0F00h to 0FFFh code protected (PIC16F874, 873)
01 = 1000h to 1FFFh code protected (PIC16F877, 876)
01 = 0800h to 0FFFh code protected (PIC16F874, 873)
00 = 0000h to 1FFFh code protected (PIC16F877, 876)
00 = 0000h to 0FFFh code protected (PIC16F874, 873)
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.
Unimplemented: Read as ‘1’

CPD: Data EE Memory Code Protection
1 = Code protection off
0 = Data EEPROM memory code protected
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
BODEN: Brown-out Reset Enable bit
1 = BOR enabled
0 = BOR disabled
PWRTE: Power-up Timer Enable bit
1 = PWRT disabled
0 = PWRT enabled
