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.
Unimplemented: Read as ‘1’
BOREN<1:0>: Brown-out Reset Selection bits
11 = BOR enabled
10 = BOR enabled during operation and disabled in Sleep
0x = BOR disabled
IOSCFS: Internal Oscillator Frequency Select bit
1 = 8 MHz
0 = 4 MHz
CP: Code Protection bit
1 = Program memory code protection is disabled
0 = Program memory code protection is enabled
MCLRE: MCLR Pin Function Select bit
1 = MCLR pin function is MCLR
0 = 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
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
100 = INTOSCIO oscillator: I/O function on RA4/OSC2/CLKOUT pin, I/O function on
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
