(b) Example of input capture operation
Figure 10.13 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.
