The PIC24FJ16MC101/102 oscillator system provides:
• External and internal oscillator options as clock
• An on-chip 4x Phase-Locked Loop (PLL) to scale
• An internal FRC oscillator that can also be used
• Clock switching between various clock sources
• Programmable clock postscaler for system power
• A Fail-Safe Clock Monitor (FSCM) that detects
• A Clock Control register (OSCCON)
• Nonvolatile Configuration bits for main oscillator
