DEVICE CONFIGURATION
Enabling Brown-out Reset does not automatically enable Power-up Timer.
The entire program memory will be erased when the code protection is turned off.
When MCLR is asserted in INTOSC or RC mode, the internal clock oscillator is disabled.
MPLAB
DEBUG: In-Circuit Debugger Mode bit
1 = In-Circuit Debugger disabled, RB6/ICSPCLK and RB7/ICSPDAT are general purpose I/O pins
0 = In-Circuit Debugger enabled, RB6/ICSPCLK and RB7/ICSPDAT are dedicated to the debugger
PLLEN: INTOSC PLL Enable bit
0 = INTOSC Frequency is 500 kHz
1 = INTOSC Frequency is 16 MHz (32x)
Unimplemented: Read as ‘1’
BORV: Brown-out Reset Voltage selection bit
0 = Brown-out Reset Voltage (V
1 = Brown-out Reset Voltage (V
BOREN<1:0>: Brown-out Reset Selection bits
0x = BOR disabled (Preconditioned State)
10 = BOR enabled during operation and disabled in Sleep
11 = BOR enabled
Unimplemented: Read as ‘1’
CP: Code Protection bit
1 = Program memory code protection is disabled
0 = Program memory code protection is enabled
MCLRE: RE3/MCLR pin function select bit
1 = RE3/MCLR pin function is MCLR
0 = RE3/MCLR pin function is digital input, MCLR internally tied to V
PWRTE: Power-up Timer Enable bit
1 = PWRT disabled
0 = PWRT enabled
WDTE: Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled

8.1
There are several Configuration Word bits that allow
different oscillator and memory protection options.
These are implemented as Configuration Word 1
register at 2007h and Configuration Word 2 register at
2008h. These registers are only accessible during
programming.
