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 and 1,
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
1. Example of Input Capture Operation Setting Procedure
Figure 9.10 shows an example of the input capture operation setting procedure.
0 and 1, MPφ/1 should not be selected as the counter input clock used for input capture
input. Input capture will not be generated if MPφ/1 is selected.
