Figure 12.13 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.
