Figure 15.12 shows an example of PWM mode operation.
In this example, TGRB compare match is set as the TCNT clearing source, 0 is set for the TGRA
initial output value and output value, and 1 is set as the TGRA output value.
In this case, the value set in TGRB is used as the period, and the value set in TGRA as the duty.
Figure 15.13 shows examples of PWM waveform output with 0% duty and 100% duty in PWM
mode.
