15.4.3 PWM Generator (PG) Features

Most of the features and controls of the PWM module are at the PWM Generator level and are controlled using each PWM Generator’s SFRs. PWM Generator operation is based on triggers. The PWM Generator must receive a Start-of-Cycle (SOC) Trigger signal to generate each PWM cycle. The trigger signal may be generated outside of the PWM Generator, or the PWM Generator may be self-triggered. When a PWM Generator reaches the end of a PWM cycle, it produces an End-of-Cycle (EOC) trigger that can be used by other PWM Generators.

If multiple PWM Generators run at different frequencies, the triggers can be synchronized using the PCI Sync block.
