PWM: PULSE-WIDTH MODULATION
If it’s needed a control over other devices via a Pulse-Width Modulation (PWM), the module offers a PWM
peripheral with 16 bits time-base with Period and Frequency control and two outputs.
Max PWM frequency is 66 MHz. More information at chapter 52 from iMX6 Applications Processor Reference
Manual.
In the next figure is shown a simple example in which the PWM signal is sent to a RC-filter.
