• Example of Input Capture Operation
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.

Designate TGR as an input capture register by
means of TIOR, and select rising edge, falling
edge, or both edges as the input capture source
and input signal edge.
