PWRTE WDTE FOSC2 FOSC1 FOSC0

bit 7 bit 0

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)

11 = BOR enabled

10 = BOR enabled during operation and disabled in Sleep

0x = BOR disabled

bit 7 IOSCFS: Internal Oscillator Frequency Select bit

1 = 8 MHz

0 = 4 MHz

bit 6 CP: Code Protection bit

(2)

1 = Program memory code protection is disabled

0 = Program memory code protection is enabled

bit 5 MCLRE: MCLR

Pin Function Select bit

(3)

1 = MCLR pin function is MCLR

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

bit 4 PWRTE: Power-up Timer Enable bit

1 = PWRT disabled

0 = PWRT enabled

bit 3 WDTE: Watchdog Timer Enable bit

1 = WDT enabled

0 = WDT disabled

bit 2-0 FOSC<2:0>: Oscillator Selection bits

111 = RC oscillator: CLKOUT function on RA4/OSC2/CLKOUT pin, RC on RA5/OSC1/CLKIN

110 = RCIO oscillator: I/O function on RA4/OSC2/CLKOUT pin, RC on RA5/OSC1/CLKIN

101 = INTOSC oscillator: CLKOUT function on RA4/OSC2/CLKOUT pin, I/O function on

RA5/OSC1/CLKIN

100 = INTOSCIO oscillator: I/O function on RA4/OSC2/CLKOUT pin, I/O function on

RA5/OSC1/CLKIN

011 = EC: I/O function on RA4/OSC2/CLKOUT pin, CLKIN on RA5/OSC1/CLKIN

010 = HS oscillator: High-speed crystal/resonator on RA4/OSC2/CLKOUT and RA5/OSC1/CLKIN

001 = XT oscillator: Crystal/resonator on RA4/OSC2/CLKOUT and RA5/OSC1/CLKIN

000 = LP oscillator: Low-power crystal on RA4/OSC2/CLKOUT and RA5/OSC1/CLKIN

Note 1: Enabling Brown-out Reset does not automatically enable Power-up Timer.

2: The entire program memory will be erased when the code protection is turned off.

3: When MCLR

is asserted in INTOSC or RC mode, the internal clock oscillator is disabled.
