8. Multi-Function Timer Pulse Unit (MTU)
Examples of PWM Mode Operation: Figure 8.21 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 values set in the TGRB registers
are used as the duty cycle.
