Reset values for these bits are determined by the FNOSC Configuration bits.
The state of the IOLOCK bit can only be changed once an unlocking sequence has been executed. In
addition, if the IOL1WAY Configuration bit is ‘1’, once the IOLOCK bit is set, it cannot be cleared.
Also resets to ‘0’ during any valid clock switch or whenever a non PLL Clock mode is selected.
NOSC<2:0>: New Oscillator Selection bits
111 = Fast RC Oscillator with Postscaler (FRCDIV)
110 = Fast RC/16 Oscillator
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)
CLKLOCK: Clock Selection Lock Enabled bit
If FSCM is enabled (FCKSM1 = 1):
1 = Clock and PLL selections are locked
0 = Clock and PLL selections are not locked and may be modified by setting the OSWEN bit
If FSCM is disabled (FCKSM1 = 0):
Clock and PLL selections are never locked and may be modified by setting the OSWEN bit.
IOLOCK: I/O Lock Enable bit
1 = I/O lock is active
0 = I/O lock is not active
LOCK: PLL Lock Status bit
1 = PLL module is in lock or PLL module start-up timer is satisfied
0 = PLL module is out of lock, PLL start-up timer is running or PLL is disabled
Unimplemented: Read as ‘0’
CF: Clock Fail Detect bit
1 = FSCM has detected a clock failure
0 = No clock failure has been detected
POSCEN: Primary Oscillator Sleep Enable bit
1 = Primary Oscillator continues to operate during Sleep mode
0 = Primary Oscillator is disabled during Sleep mode
SOSCEN: 32 kHz Secondary Oscillator (SOSC) Enable bit
1 = Enable the Secondary Oscillator
0 = Disable the Secondary Oscillator
OSWEN: Oscillator Switch Enable bit
1 = Initiate an oscillator switch to the clock source specified by the NOSC<2:0> bits
0 = Oscillator switch is complete
