6.17.3.10 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 differente count type as shown in Figure
6.17-8.

Figure 6.17-8 PWM Pulse Generation in Up-Down Count Type
The PWM generation events may sometimes generated at the same time, as the reason, events
priority between different counter types should be take care are list in below tables. Table 6.17-9
is for event priority in up count type. Table 6.17-10 is for event priority in down count type and
Table 6.17-11 is for event priority in up-down count type.
