CONFIG (address:0x0FFF, mask:0x001F, default:0x001F)
OSC -- Oscillator Selection bits (bitmask:0x0003)
OSC = LP | 0x0FFC | LP oscillator.
OSC = XT | 0x0FFD | XT oscillator.
OSC = IntRC | 0x0FFE | internal RC oscillator.
OSC = ExtRC | 0x0FFF | external RC oscillator.
WDT -- Watchdog Timer Enable bit (bitmask:0x0004)
WDT = OFF | 0x0FFB | WDT disabled.
WDT = ON | 0x0FFF | WDT enabled.
CP -- Code Protection bit (bitmask:0x0008)
CP = ON | 0x0FF7 | Code protection on.
CP = OFF | 0x0FFF | Code protection off.
MCLRE -- GP3/MCLR Pin Function Select bit (bitmask:0x0010)
MCLRE = OFF | 0x0FEF | GP3/MCLR pin function is digital input, MCLR internally tied to VDD.
MCLRE = ON | 0x0FFF | GP3/MCLR pin function is MCLR.
