(b) Example of input capture operation
11.4.2
In synchronous operation, the values in multiple TCNT counters can be rewritten simultaneously
(synchronous presetting). Also, multiple of TCNT counters can be cleared simultaneously
(synchronous clearing) by making the appropriate setting in TCR.
Synchronous operation enables TGR to be incremented with respect to a single time base.
Channels 0 to 5 and 6 to 11 can all be designated for synchronous operation.

Figure 11.10 shows an example of input capture operation.
In this example both rising and falling edges have been selected as the TIOCA pin input
capture input edge, falling edge has been selected as the TIOCB pin input capture input edge,
and counter clearing by TGRB input capture has been designated for TCNT.
