Unimplemented: Read as ‘0’
MCLRE: RB3/MCLR Pin Function Select bit
1 = RB3/MCLR pin function is MCLR
0 = RB3/MCLR pin function is digital input, MCLR internally tied to V
CP: Code Protection bit
1 = Code protection off
0 = Code protection on
WDTE: Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled
