Vault 7: Projects
This publication series is about specific projects related to the Vault 7 main publication.
PIC24FJ64GA004 FAMILY
DS39881E-page 98 2010-2013 Microchip Technology Inc.
bit 7 CLKLOCK: Clock Selection Lock Enable 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.
bit 6 IOLOCK: I/O Lock Enable bit
(2)
1 = I/O lock is active
0 = I/O lock is not active
bit 5 LOCK: PLL Lock Status bit
(3)
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
bit 4 Unimplemented: Read as 0
bit 3 CF: Clock Fail Detect bit
1 = FSCM has detected a clock failure
0 = No clock failure has been detected
bit 2 Unimplemented: Read as 0
bit 1 SOSCEN: 32 kHz Secondary Oscillator (SOSC) Enable bit
1 = Enables Secondary Oscillator
0 = Disables Secondary Oscillator
bit 0 OSWEN: Oscillator Switch Enable bit
1 = Initiates an oscillator switch to a clock source specified by the NOSC<2:0> bits
0 = Oscillator switch is complete
REGISTER 8-1: OSCCON: OSCILLATOR CONTROL REGISTER (CONTINUED)
Note 1: Reset values for these bits are determined by the FNOSCx Configuration bits.
2: 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.
3: Also resets to 0 during any valid clock switch or whenever a non-PLL Clock mode is selected.
