6.7.6.10 PWM Pulse Generator
PWM pulse generator uses counter and comparator events to generate PWM output pulse. The
events are zero point and period point in up count type and down count type, center point in up-
down count type and counter equal to comparator point in three count types.
Each event point can generate PWM output waveform in different count type as shown in Figure
6.7-20.
