(3) 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
0 and 1, P/1 should not be selected as the counter input clock used for input capture
input. Input capture will not be generated if P/1 is selected.
(a) Example of Input Capture Operation Setting Procedure
Figure 11.10 shows an example of the input capture operation setting procedure.

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