Writes to this register require an unlock sequence. Refer to Section 6. “Oscillator” (DS39700) in the
“PIC24F Family Reference Manual” 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.
