• Manufacturer: Hitachi

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
Example of input capture operation setting procedure
Figure 10-12 shows an example of the input capture operation setting procedure.

Select input capture input
0 and 3, ø/1 should not be selected as the counter input clock used for input capture input.
Input capture will not be generated if ø/1 is selected.
