Section 9 Timers
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.
