3.18.3 Clock Generator (CLOCK)

The PIC32MX clock system has the following modules and features:

  • A total of five external and internal oscillator options as clock sources

  • On-Chip PLL with user-selectable input divider, multiplier and output divider to boost operating frequency on select internal and external oscillator sources

  • On-Chip user-selectable divisor postscaler on select oscillator sources

  • Software-controllable switching between various clock sources

  • A Fail-Safe Clock Monitor (FSCM) that detects clock failure and permits safe application recovery

  • Dedicated On-Chip PLL for USB peripheral

  • Flexible reference clock output

  • Multiple clock branches for peripherals for better performance flexibility
