(2) Example of Synchronous Operation
Figure 19.13 shows an example of synchronous operation.
In this example, synchronous operation and PWM mode 1 have been designated for MTU0 to MTU 2, MTU0.TGRB
compare match has been set as the counter clearing source in MTU0, and synchronous clearing has been set for the
counter clearing source in MTU1 and MTU2.
Three-phase PWM waveforms are output from pins MTIOC0A, MTIOC1A, and MTIOC2A. At this time, synchronous
setting and synchronous clearing by MTU0.TGRB compare match are performed for the TCNT counters in MTU0 to
MTU2, and the data set in MTU0.TGRB is used as the PWM period.
For details of PWM modes, refer to section 19.3.5, PWM Modes .
