10-Int-3 68HC12 PWM PWM subsystem provides four independent 8-bit PWM waveforms or two 16-bit PWM waveforms or A combination of one 16-bit and two 8-bit PWM waveforms. Each waveform channel has a programmable period and a programmable duty cycle as well as a dedicated counter. A flexible clock select scheme allows four different clock sources to be used with the counters. Each of the modulators can create independent, continuous waveforms with software-selectable duty rates from 0 percent to 100 percent. The PWM outputs can be programmed as left-aligned
