The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/
50X, and PIC24EPXXXGP/MC20X oscillator system
provides:
• On-chip Phase-Locked Loop (PLL) to boost inter-
• On-the-fly clock switching between various clock
• Doze mode for system power savings
• Fail-Safe Clock Monitor (FSCM) that detects clock
• Configuration bits for clock source selection
