Writes to this register require an unlock sequence. Refer to Section 39. “Oscillator (Part III)” (DS70308)
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).

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
