Example of Synchronous Operation: Figure 10.15 shows an example of synchronous operation.
In this example, synchronous operation and PWM mode 1 have been designated for channels 0 to
2, TGR0B compare match has been set as the channel 0 counter clearing source, and synchronous
clearing has been set for the channel 1 and 2 counter clearing source.
Three-phase PWM waveforms are output from pins TIOC0A, TIOC1A, and TIOC2A. At this
time, synchronous presetting, and synchronous clearing by TGR0B compare match, is performed
for channel 0 to 2 TCNT counters, and the data set in TGR0B is used as the PWM cycle.
For details of PWM modes, see section 10.4.6, PWM Modes.
