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 12.16 shows an example of the input capture operation setting procedure.

[1] Designate GR as an input capture

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.
