Figure 9.11 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, the 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.
