OSCILLATOR
CONFIGURATION
The dsPIC33FJXXXGPX06/X08/X10 oscillator system
provides:
Various external and internal oscillator options as
clock sources
An on-chip PLL to scale the internal operating
frequency to the required system clock frequency
The internal FRC oscillator can also be used with
the PLL, thereby allowing full-speed operation
without any external clock generation hardware
Clock switching between various clock sources
Programmable clock postscaler for system power
savings
A Fail-Safe Clock Monitor (FSCM) that detects
clock failure and takes fail-safe measures
A Clock Control register (OSCCON)
Nonvolatile Configuration bits for main oscillator
selection.
A simplified diagram of the oscillator system is shown
