12. Pulse Width Modulation Controller (PWM)

The PWM controls four channels independently. Each Channel controls two complementary square output waveforms. Characteristics of the output waveforms such as period, duty-cycle, polarity and dead-times are configured through the user interface. Each channel selects and uses one of the clocks provided by the clock generator. The clock generator provides several clocks resulting from the division of the PWM master clock (MCK).
