3. Input Capture Input Timing
a. Without noise cancellation function
For input capture input, dedicated input capture functions are provided for rising and falling
edges.
Figure 9.11 shows the timing for rising/falling edge input capture input.

b. With noise cancellation function
When noise cancellation is performed on the input capture input, the passage of the input
capture signal through the noise canceler results in a delay of five sampling clock cycles from
the input capture input signal edge.
Figure 9.12 shows the timing in this case.
