High-Performance, 16-bit Microcontrollers

Microchip Technology 

PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 AND PIC24HJ128GPX02/X04

REGISTER 9-1: OSCCON: OSCILLATOR CONTROL REGISTER(1) (CONTINUED)

bit 2

Unimplemented: Read as ‘0’

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 39. “Oscillator (Part III)” (DS70308)

in the “dsPIC33F Family Reference Manual” (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.
