9.1 Clock Distribution

The clock system of the PIC32CM6408PL10 device consists of several clock sources, the Generic Clock Generator module (GCLK), and the Main Clock module (MCLK), each containing its own control logic.

A clock source provides a time base that is used by the peripherals in the device. The GCLK module clocks the majority of the device’s peripherals, with a few exceptions. The MCLK module clocks the CPU. Some peripherals are clocked directly from the clock sources.

The figure below provides an overview of the clock system.
