PWM uses a square wave with constant frequency whose duty cycle is modulated resulting in an average value
of the waveform.
Figure 21
duty cycle of a PWM is defined by following general formulas:
The range between 0 - 6.25% and 93.75 - 100% is used only for diagnostic purposes. More details are given in
