6.8.5.20 PWM Output Control
After PWM pulse generation, there are four to six steps to control the output of PWM channels. In
independent mode, there are Mask, Brake, Pin Polarity and Output Enable four steps as shown in
Figure 6.8-26. In complementary mode, it needs two more steps to precede these four steps,
Complementary channels and Dead-Time Insertion as shown in Figure 6.8-27.
