bit 1
LPOSCEN: Secondary (LP) Oscillator Enable bit
1 = Enable secondary oscillator
0 = Disable secondary oscillator
bit 0
OSWEN: Oscillator Switch Enable bit
1 = Request oscillator switch to selection specified by NOSC<2:0> bits
0 = Oscillator switch is complete
Note 1:

Writes to this register require an unlock sequence. Refer to Section 7. âOscillatorâ (DS70186) in the
âdsPIC33F/PIC24H Family Reference Manualâ (available from the Microchip web site) for details.
Direct clock switches between any primary oscillator mode with PLL and FRCPLL modes 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.
