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.
Note: When another channel’s counter input clock is used as the input capture input for channel

Figure 12.12 shows an example of the setting procedure for input capture operation.
0, φ/1 should not be selected as the counter input clock used for input capture input. Input
capture will not be generated if φ/1 is selected. Another channel’s counter input clock or
compare-match signal can be used as the input capture source for channels 0 and 1.

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.
Set the CST bit in TSTR to 1 to start the count
operation.
