Examples of PWM Mode Operation: Figure 9.22 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 TGRB registers as the duty.
Figure 9.23 shows an example of PWM mode 2 operation. In this example, synchronous operation
is designated for channels 0 and 1, TGRB_1 compare match is set as the TCNT clearing source,
and 0 is set for the initial output value and 1 for the output value of the other TGR registers
(TGRA_0 to TGRD_0, TGRA_1), to output a 5-phase PWM waveform. In this case, the value set
in TGRB_1 is used as the cycle, and the values set in the other TGRs as the duty.
