Example of Synchronous Operation:
Figure 12.15 shows an example of synchronous operation.
In this example, synchronous operation and PWM mode 1 have been designated for channels 0 to
2, TGRB_0 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 TIOCA0, TIOCA1, and TIOCA2. At this
time, synchronous presetting, and synchronous clearing by TGRB_0 compare match, are
performed for the TCNT counters in channels 0 to 2, and the data set in TGRB_0 is used as the
PWM cycle.
For details on PWM modes, see section 12.5.5, PWM Modes.
