Section 10 16-Bit Timer Pulse Unit (TPU)
Examples of PWM Mode Operation: Figure 10.25 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.
