DEVICE CONFIGURATION

Device Configuration consists of Configuration Word 1

and Configuration Word 2 registers, Code Protection

and Device ID.

8.1

Configuration Words

There are several Configuration Word bits that allow

different oscillator and memory protection options.

These are implemented as Configuration Word 1

2008h. These registers are only accessible during

programming.

Legend:

P = Programmable bit

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 13

DEBUG: In-Circuit Debugger Mode bit

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

= In-Circuit Debugger enabled, RB6/ICSPCLK and RB7/ICSPDAT are dedicated to the debugger

bit 12

PLLEN: INTOSC PLL Enable bit

= INTOSC Frequency is 500 kHz

= INTOSC Frequency is 16 MHz (32x)

bit 11

Unimplemented: Read as ‘1’

bit 10

BORV: Brown-out Reset Voltage selection bit

= Brown-out Reset Voltage (VBOR) set to 2.5 V nominal

= Brown-out Reset Voltage (VBOR) set to 1.9 V nominal

bit 9-8

BOREN<1:0>: Brown-out Reset Selection bits(1)

= BOR disabled (Preconditioned State)

= BOR enabled during operation and disabled in Sleep

= BOR enabled

bit 7

Unimplemented: Read as ‘1’

bit 6

CP: Code Protection bit(2)

= Program memory code protection is disabled

= Program memory code protection is enabled

bit 5

MCLRE: RE3/MCLR pin function select bit(3)

= RE3/MCLR pin function is MCLR

= RE3/MCLR pin function is digital input, MCLR internally tied to VDD

bit 4

PWRTE: Power-up Timer Enable bit

= PWRT disabled

= PWRT enabled

bit 3

WDTE: Watchdog Timer Enable bit

= WDT enabled

= WDT disabled

Note

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® IDE masks unimplemented Configuration bits to ‘0’.
