bit 13-12:

bit 5-4:

CP<1:0>:

Flash Program Memory Code Protection bits

(2)

= Code protection off

= Not supported

= Code protection on

DEBUG:

In-Circuit Debugger Mode

= In-Circuit Debugger disabled, RB6 and RB7 are general purpose I/O pins.

= In-Circuit Debugger enabled, RB6 and RB7 are dedicated to the debugger.

Unimplemented: Read as 鈥?鈥?/div>

WRT:

Flash Program Memory Write Enable

= Unprotected program memory may be written to by EECON control

= Unprotected program memory may not be written to by EECON control

CPD:

Data EE Memory Code Protection

= Code protection off

= Data EEPROM memory code protected

LVP:

Low Voltage In-Circuit Serial Programming Enable bit

= RB3/PGM pin has PGM function, low voltage programming enabled

= RB3 is digital I/O, HV on MCLR must be used for programming

BODEN:

Brown-out Reset Enable bit

(1)

= BOR enabled

= BOR disabled

PWRTE:

Power-up Timer Enable bit

(1)

= PWRT disabled

= PWRT enabled

WDTE:

Watchdog Timer Enable bit

= WDT enabled

= WDT disabled

FOSC1:FOSC0:

Oscillator Selection bits

= RC oscillator

= HS oscillator

= XT oscillator

= LP oscillator

bit 9:

bit 8:

bit 7:

bit 6:

bit 3:

bit 2:

bit 1-0:

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.

All of the CP<1:0> pairs have to be given the same value to enable the code protection scheme listed.
