(2) Example of Synchronous Operation

Figure 10.11 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 channel 0 to 2 TCNT counters, and the data set in TGRB_0 is used as the PWM cycle.

For details on PWM modes, see section 10.4.5, PWM Modes.
