The dsPIC33FJXXXGPX06A/X08A/X10A oscillator
system provides:
• Various external and internal oscillator options as
• An on-chip PLL to scale the internal operating
• The internal FRC oscillator can also be used with
• Clock switching between various clock sources
• Programmable clock postscaler for system power
• A Fail-Safe Clock Monitor (FSCM) that detects
• An Oscillator Control register (OSCCON)
• Nonvolatile Configuration bits for main oscillator
