Legend:

R = Readable bit

P = Programmable bit

U = Unimplemented bit, read as ‘1’

‘0’ = Bit is cleared

‘1’ = Bit is set

-n = Value when blank or after Bulk Erase

bit 13

DEBUG: Debug Mode Enable bit(2)

= Background debugger is disabled

= Background debugger is enabled

bit 12

CLKOUTEN: Clock Out Enable bit

= Clock out function disabled. CLKOUT pin acts as I/O pin

= Clock out function disabled. CLKOUT pin acts as CLKOUT

bit 11-10

WRT<1:0>: Flash Program Memory Self Write Enable bit

= Write protection off

= 000h to FFh write-protected, 100h to 3FFh may be modified by PMCON1 control

= 000h to 1FFh write-protected, 200h to 3FFh may be modified by PMCON1 control

= 000h to 3FFh write-protected, entire program is write-protected

bit 8-9

BOREN<1:0>: Brown-out Reset Enable bits

= BOR enabled

= BOR enabled during operation and disabled in Sleep

= BOR disabled

bit 7

Unimplemented: Read as ‘1’.

bit 6

CP: Code Protection bit

= Program memory code protection is disabled

= Program memory code protection is enabled

bit 5

MCLRE: MCLR/VPP Pin Function Select bit

= MCLR pin is MCLR function and weak internal pull-up is enabled

= MCLR pin is input function, MCLR function is internally disabled

bit 4

PWRTE: Power-up Timer Enable bit(1)

= PWRT disabled

= PWRT enabled

bit 3

WDTE: Watchdog Timer Enable bit

= WDT enabled

= WDT disabled

bit 2-1

Unimplemented: Read as ‘1’.

bit 0

FOSC: Oscillator Selection bits

= EC oscillator selected: CLKIN on RA5/CLKIN

= Internal oscillator: I/O function on RA5/CLKIN

Note 1:

Enabling Brown-out Reset does not automatically enable Power-up Timer.

The Configuration bit is managed automatically by the device development tools. The user should not

attempt to manually write this bit location. However, the user should ensure that this location has been

programmed to a ‘1’ and the device checksum is correct for proper operation of production software.
