MCLRE: MCLR Pin Enable bit
1 = MCLR pin enabled, RA5 input pin disabled
0 = RA5 input pin enabled, MCLR pin disabled
Unimplemented: Read as ‘0’
LPT1OSC: Low-Power Timer1 Oscillator Enable bit
1 = Timer1 configured for low-power operation
0 = Timer1 configured for higher power operation
PBADEN: PORTB A/D Enable bit
(Affects ADCON1 Reset state. ADCON1 controls PORTB<4:0> pin configuration.)
1 = PORTB<4:0> pins are configured as analog input channels on Reset
0 = PORTB<4:0> pins are configured as digital I/O on Reset
Unimplemented: Read as ‘0’
