bit 13-7 CP0: Code protection bits
5-4: 1 = Code protection off
0 = All memory is code protected, but 00h - 3Fh is writable

BODEN: Brown-out Reset Enable bit
1 = BOR enabled
0 = BOR disabled
(1)
PWRTE: Power-up Timer Enable bit
1 = PWRT disabled
0 = PWRT enabled
WDTE: 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
Note 1: Enabling Brown-out Reset automatically enables Power-up Timer (PWRT) regardless of the value of bit PWRTE.
Ensure the Power-up Timer is enabled anytime Brown-out Reset is enabled.
2: All of the CP0 bits have to be given the same value to enable the code protection scheme listed.
