oscillator source when ready
0 = Start-Up device with user-selected oscillator source
FNOSC<2:0>
FOSCSEL
Initial Oscillator Source Selection bits
111 = Internal Fast RC (FRC) oscillator with postscaler
110 = Internal Fast RC (FRC) oscillator with divide-by-16
101 = LPRC oscillator
100 = Secondary (LP) oscillator
011 = Primary (XT, HS, EC) oscillator with PLL
010 = Primary (XT, HS, EC) oscillator

FCKSM<1:0>
FOSC
Clock Switching Mode bits
1x = Clock switching is disabled, Fail-Safe Clock Monitor is disabled
01 = Clock switching is enabled, Fail-Safe Clock Monitor is disabled
00 = Clock switching is enabled, Fail-Safe Clock Monitor is enabled
IOL1WAY
FOSC
Peripheral Pin Select Configuration
1 = Allow only one reconfiguration
