Examples of PWM Mode Operation: Figure 14.12 shows an example of PWM mode operation.
In this example, TGRB compare match is set as the TCNT clearing source, 0 is set as the initial
output value of the TO pin by TGRA, and 1 is set as the output value by TGRA compare match.
In this case, the value set in TGRB is used as the period, and the value set in TGRA as the duty.
Figure 14.13 shows examples of PWM waveform output with 0% duty and 100% duty in PWM
mode.
