Reserved: Read as ’1’
OSCSEN: Oscillator System Clock Switch Enable bit
1 = Oscillator system clock switch option is disabled (main oscillator is source)
0 = Oscillator system clock switch option is enabled (oscillator switching is enabled)
Unimplemented: Read as ’0’
FOSC2:FOSC0: Oscillator Selection bits
111 = RC oscillator w/OSC2 configured as RA6
110 = HS oscillator with PLL enabled/Clock frequency = (4 x FOSC)
101 = EC oscillator w/OSC2 configured as RA6
100 = EC oscillator w/OSC2 configured as divide-by-4 clock output
011 = RC oscillator
