Pulse-Width Modulation (PWM) Module
This chapter describes the configuration and operation of the pulse-width modulation (PWM) module. It
includes a block diagram, programming model, and timing diagram.
18.1
Overview
The PWM module shown in
Figure
18-1, generates a synchronous series of pulses having programmable
duty cycle. With a suitable low-pass filter, the PWM can be used as a digital-to-analog converter.
