dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04
REGISTER 8-1: OSCCON: OSCILLATOR CONTROL REGISTER(1) (CONTINUED)
bit 3
CF: Clock Fail Detect bit (read/clear by application)
1 = FSCM has detected clock failure
0 = FSCM has not detected clock failure
bit 2-1
Unimplemented: Read as â0â
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 42. âOscillator (Part IV)â (DS70307)
in the âdsPIC33F Family Reference Manualâ (available from the Microchip website) for details.
2: 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.
