Section 18 Multi-Function Timer Pulse Unit (MTU)
Counter Clearing by another Channel: In complementary PWM mode, by setting a mode for
synchronization with another channel by means of the timer synchro register (TSYR), and
selecting synchronous clearing with bits CCLR2 to CCLR0 in the timer control register (TCR), it
is possible to have TCNT_3, TCNT_4, and TCNTS cleared by another channel.
Figure 18.49 illustrates the operation.
Use of this function enables counter clearing and restarting to be performed by means of an
external signal.
