Writes to this register require an unlock sequence. Refer to Section 7. “Oscillator” (DS70580) in the
“dsPIC33E/PIC24E Family Reference Manual” (available from the Microchip web site) 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 resets only on a Power-on Reset (POR).
CF: Clock Fail Detect bit (read/clear by application)
1 = FSCM has detected clock failure
0 = FSCM has not detected clock failure
Unimplemented: Read as ‘0’
LPOSCEN: Secondary (LP) Oscillator Enable bit
1 = Enable Secondary Oscillator
0 = Disable Secondary Oscillator
OSWEN: Oscillator Switch Enable bit
1 = Request oscillator switch to selection specified by NOSC<2:0> bits
0 = Oscillator switch is complete
OSCCON: OSCILLATOR CONTROL REGISTER
