• Manufacturer Part Number: dspic33fj128gp204
• Description: High-performance, 16-bit Digital Signal Controllers
• Manufacturer: Microchip Technology Inc.

REGISTER 9-1:
DS70292C-page 142
bit 2
bit 1
bit 0
Note 1: Writes to this register require an unlock sequence. Refer to Section 39. “Oscillator (Part III)” (DS70216)
2: Direct clock switches between any primary oscillator mode with PLL and FRCPLL mode are not permitted.
in the “dsPIC33F Family Reference Manual” (available from the Microchip website) for details.
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.
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
