Legend:

R = Readable bit

W = Writable bit

P = Programmable’

U = Unimplemented bit,

read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 15-10

Unimplemented: Read as ‘1’

bit 9-8

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

= BOR enabled

= BOR enabled during operation and disabled in Sleep

= BOR disabled

bit 7

IOSCFS: Internal Oscillator Frequency Select bit

= 8 MHz

= 4 MHz

bit 6

CP: Code Protection bit(2)

= Program memory code protection is disabled

= Program memory code protection is enabled

bit 5

MCLRE: MCLR Pin Function Select bit(3)

= MCLR pin function is MCLR

= 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

bit 2-0

FOSC<2:0>: Oscillator Selection bits

111

= RC oscillator: CLKOUT function on GP4/OSC2/CLKOUT pin, RC on GP5/OSC1/CLKIN

110

= RCIO oscillator: I/O function on GP4/OSC2/CLKOUT pin, RC on GP5/OSC1/CLKIN

101

= INTOSC oscillator: CLKOUT function on GP4/OSC2/CLKOUT pin, I/O function on

GP5/OSC1/CLKIN

100

= INTOSCIO oscillator: I/O function on GP4/OSC2/CLKOUT pin, I/O function on

GP5/OSC1/CLKIN

011

= EC: I/O function on GP4/OSC2/CLKOUT pin, CLKIN on GP5/OSC1/CLKIN

010

= HS oscillator: High-speed crystal/resonator on GP4/OSC2/CLKOUT and GP5/OSC1/CLKIN

001

= XT oscillator: Crystal/resonator on GP4/OSC2/CLKOUT and GP5/OSC1/CLKIN

000

= LP oscillator: Low-power crystal on GP4/OSC2/CLKOUT and GP5/OSC1/CLKIN

Note 1:

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.
