M0564
6.13 PWM Generator and Capture Timer (PWM)
6.13.1 Overview
The M0564 provides two PWM generator: PWM0 and PWM1. Each PWM supports 6 channels of
PWM output or input capture. There is a 12-bit prescaler to support flexible clock to the 16-bit
PWM counter with 16-bit comparator. The PWM counter supports up, down and up-down counter
types. PWM uses comparator compared with counter to generate events. These events use to
generate PWM pulse, interrupt and trigger signal for ADC to start conversion.
The PWM generator supports two standard PWM output modes: Independent mode and
Complementary mode, they have difference architecture. There are two output functions based
on standard output modes: Group function and Synchronous function. Group function can be
enabled under Independent mode or complementary mode. Synchronous function only enabled
under complementary mode. Complementary mode has two comparators to generate various
PWM pulse with 12-bit dead-time generator and another free trigger comparator to generate
trigger signal for ADC. For PWM output control unit, it supports polarity output, independent pin
mask and brake functions.
The PWM generator also supports input capture function. It supports latch PWM counter value to
corresponding register when input channel has a rising transition, falling transition or both
transition is happened. Capture function also support PDMA to transfer captured data to memory.
