Example of input capture operation: Figure 9.13 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.
9.4.3
In synchronous operation, the values in a number of TCNT counters can be rewritten
simultaneously (synchronous presetting). Also, a number of TCNT counters can be cleared
simultaneously by making the appropriate setting in TCR (synchronous clearing).
Synchronous operation enables TGR to be incremented with respect to a single time base.
Channels 0 to 2 can all be designated for synchronous operation.
