POSCMD1 POSCMD0
bit 0
Legend:
x = Bit is unknown
R = Readable bit
PO = Program Once bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
‘1’ = Bit is set
‘0’ = Bit is cleared

bit 5
bit 4-2
bit 1-0
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
Unimplemented: Read as ‘1’
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: OSC2 Pin Configuration bit
If POSCMD<1:0> = 11 or 00:
1 = OSC2/CLKO/RC15 functions as CLKO (FOSC/2)
0 = OSC2/CLKO/RC15 functions as port I/O (RC15)
If POSCMD<1:0> = 10 or 01:
OSCIOFCN has no effect on OSC2/CLKO/RC15.
Unimplemented: Read as ‘1’
POSCMD<1:0>: Primary Oscillator Configuration bits
11 = Primary oscillator is disabled
10 = HS Oscillator mode is selected
01 = XT Oscillator mode is selected
00 = EC Oscillator mode is selected
