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

Figure 11.9 shows an example of the setting procedure for input capture operation.
Figure 11.10 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.
* Not available in the H8S/2227 Group.
0 and 3, 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.

Designate TGR as an input capture register by
means of TIOR, and select the input capture source
and input signal edge (rising edge, falling
edge, or both edges).
Set the CST bit in TSTR to 1 to start the count
operation.
