The
PIC24EPXXXGU810/814 oscillator system provides:
• Four external and internal oscillator options
• Auxiliary oscillator that provides clock source to
• 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
• Nonvolatile Configuration bits for clock source
