• Examples of PWM Mode Operation
Figure 12.25 shows an example of PWM mode 1 operation.
In this example, TGRA 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 TGRB output value. In this
case, the value set in TGRA is used as the period, and the value set in TGRB as the duty.
