Input Capture Function: The TCNT value can be transferred to TGR on detection of the TIOC pin input edge.
Rising edge, falling edge, or both edges can be selected as the detected edge. For channels 0, 1, 3, and 4, it is also possible
to specify another channel’s counter input clock or compare match signal as the input capture source.
Note: When another channel’s counter input clock is used as the input capture input for channels 0 and 3, ø/1 should not
Figure 10-11 shows an example of toggle output.
In this example TCNT has been designated as a periodic counter (with counter clearing performed by compare match
B), and settings have been made so that output is toggled by both compare match A and compare match B.
