(m) Counter Clearing by Another Channel
In complementary PWM mode, MTU3.TCNT, MTU4.TCNT, and TCNTSA can be cleared by another channel source
when a mode for synchronization with another channel is specified through the TSYRA register and synchronous
clearing is selected with MTU3.TCR.CCLR[2:0] bits.
Figure 19.62 illustrates an example of this operation.
Use of this function enables a counter to be cleared and restarted through an external signal.
