The PIC24HJ32GP202/204 and PIC24HJ16GP304
oscillator system provides:
• External and internal oscillator options as clock
• An on-chip PLL to scale the internal operating
• 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
• An Oscillator Control register (OSCCON)
• Nonvolatile Configuration bits for main oscillator
