13. Counter Clearing by Another Channel

Input capture A
In complementary PWM mode, by setting a mode for synchronization with another channel by
means of the timer synchronous 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 9.55 illustrates the operation.
Use of this function enables counter clearing and restarting to be performed by means of an
external signal.
