Unimplemented: Read as ‘1’
IESO: Internal External Switchover bit
1 = IESO mode (Two-Speed Start-up) is enabled
0 = IESO mode (Two-Speed Start-up) is disabled
PLLDIV<2:0>: 96 MHz PLL Prescaler Select bits
111 = Oscillator input is divided by 12 (48 MHz input)
110 = Oscillator input is divided by 8 (32 MHz input)
101 = Oscillator input is divided by 6 (24 MHz input)
100 = Oscillator input is divided by 5 (20 MHz input)
011 = Oscillator input is divided by 4 (16 MHz input)
010 = Oscillator input is divided by 3 (12 MHz input)
001 = Oscillator input is divided by 2 (8 MHz input)
000 = Oscillator input is used directly (4 MHz input)
PLL96MHZ: 96 MHz PLL Start-Up Enable bit
1 = 96 MHz PLL is enabled automatically on start-up
0 = 96 MHz PLL is software controlled (can be enabled by setting the PLLEN bit in CLKDIV<5>)
FNOSC<2:0>: Initial Oscillator Select bits
111 = Fast RC Oscillator with Postscaler (FRCDIV)
110 = Reserved
101 = Low-Power RC Oscillator (LPRC)
100 = Secondary Oscillator (SOSC)
011 = Primary Oscillator with PLL module (XTPLL, HSPLL, ECPLL)
010 = Primary Oscillator (XT, HS, EC)
001 = Fast RC Oscillator with Postscaler and PLL module (FRCPLL)
000 = Fast RC Oscillator (FRC)
FCKSM<1:0>: Clock Switching and Fail-Safe Clock Monitor Configuration bits
1x = Clock switching and Fail-Safe Clock Monitor are disabled
01 = Clock switching is enabled, Fail-Safe Clock Monitor is disabled
00 = Clock switching is enabled, Fail-Safe Clock Monitor is enabled
OSCIOFCN: OSCO Pin Configuration bit
If POSCMD<1:0> = 11 or 00:
1 = OSCO/CLKO/RC15 functions as CLKO (F
0 = OSCO/CLKO/RC15 functions as port I/O (RC15)
If POSCMD<1:0> = 10 or 01:
OSCIOFCN has no effect on OSCO/CLKO/RC15.
