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, 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 TIOC0A, TIOC1A, and TIOC2A. At this time,
synchronous presetting, and synchronous clearing by TGRB_0 compare match, is performed for
channel 0 to 2 TCNT counters, and the data set in TGRB_0 is used as the PWM cycle. For details
of PWM modes, see section 10.5.4, PWM Modes.
