Section 11 16-Bit Timer Pulse Unit (TPU)
Example of Synchronous Operation: Figure 11.12 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 TIOCA2, TIOCA1, and TIOCA0. 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.

Set to 1 the SYNC bits in TSYR corresponding to the channels to be designated for synchronous operation.
When the TCNT counter of any of the channels designated for synchronous operation is written to, the same value is
simultaneously written to the other TCNT counters.
Use bits CCLR2 to CCLR0 in TCR to specify TCNT clearing by input capture/output compare, etc.
Use bits CCLR2 to CCLR0 in TCR to designate synchronous clearing for the counter clearing source.
Set to 1 the CST bits in TSTR for the relevant channels, to start the count operation.
