bit13 bit0

bit 13-7 CP0: Code protection bits

(2)

5-4: 1 = Code protection off

0 = All memory is code protected, but 00h - 3Fh is writable

bit 6: BODEN: Brown-out Reset Enable bit

(1)

1 = BOR enabled

0 = BOR disabled

bit 3: PWRTE: Power-up Timer Enable bit

(1)

1 = PWRT disabled

0 = PWRT enabled

bit 2: 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.

5-4: 11 = Code protection off

10 = Upper half of program memory code protected

01 = Upper 3/4th of program memory code protected

00 = All memory is code protected

bit 7: MPEEN: Memory Parity Error Enable

1 = Memory Parity Checking is enabled

0 = Memory Parity Checking is disabled
