9 Pulse Width Modulator

9.1 Overview

This section specifies in detail the functionality provided by the device Pulse Width Modulator

(PWM) peripheral.

The PWM controller incorporates the following features:

• Two independent output bit-streams, clocked at a fixed frequency.

• Bit-streams configured individually to output either PWM or a serialised version of a

32-bit word.

• PWM outputs have variable input and output resolutions.

• Serialise mode configured to load data to and/or read data from a FIFO storage block,

which can store up to eight 32-bit words.

• Both modes clocked by clk_pwm which is nominally 100MHz, but can be varied by

the clock manager.
