Input Capture Function

The TCNT value can be transferred to GR on detection of the input edge of the input

capture/output compare pin (FTIOA, FTIOB, FTIOC, or FTIOD). Rising edge, falling edge, or

both edges can be selected as the detected edge. When the input capture function is used, the pulse

width or period can be measured.

Figure 14.16 shows an example of the input capture operation setting procedure.

[1]

Designate GR as an input capture register by

means of TIOR, and select rising edge, falling

edge, or both edges as the input edge of the

input capture signal.

[2]

Set the STR bit in TSTR to 1 to start the TCNT

counter operation.
