Input Capture Operation: Figure 12.14 shows input capture. The falling edge of TIOCB and
both edges of TIOCA are selected as input capture input edges. In the example, TCNT is set to
clear at the input capture of the TGRB register.

12.4.3 Synchronous Operation
In the synchronizing mode, two or more timer counters can be rewritten simultaneously
(synchronized preset). Multiple timer counters can also be cleared simultaneously using TCR
settings (synchronized clear).
The synchronizing mode can increase the number of TGR registers for a single time base. All five
channels can be set for synchronous operation.
