8. Multi-Function Timer Pulse Unit (MTU)
Example of Synchronous Operation: Figure 8.12 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, are 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 8.4.5, PWM Modes.
