Writes to this register require an unlock sequence. Refer to Section 39. “Oscillator (Part III)” (DS70216)
in the “dsPIC33F/PIC24H Family Reference Manual” (available from the Microchip website) for details.
Direct clock switches between any primary oscillator mode with PLL and FRCPLL mode are not permitted.
This applies to clock switches in either direction. In these instances, the application must switch to FRC
mode as a transition clock source between the two PLL modes.
This register is reset only on a Power-on Reset (POR).

CLKLOCK: Clock Lock Enable bit
If clock switching is enabled and FSCM is disabled, FCKSM<1:0>(FOSC<7:6>) = 0b01
1 = Clock switching is disabled, system clock source is locked
0 = Clock switching is enabled, system clock source can be modified by clock switching
IOLOCK: Peripheral Pin Select Lock bit
1 = Peripherial pin select is locked, write to peripheral pin select registers not allowed
0 = Peripherial pin select is not locked, write to peripheral pin select registers allowed
LOCK: PLL Lock Status bit (read-only)
1 = Indicates that PLL is in lock, or PLL start-up timer is satisfied
0 = Indicates that PLL is out of lock, start-up timer is in progress or PLL is disabled
Unimplemented: Read as ‘0’
