A timing example of noise elimination performed by the timer AA input pin digital filter is shown Figure 7-2.
Noise elimination clock
Remark
Internal signal
Input signal
If there are two or fewer noise elimination clocks while the TIAAn0 or TIAAn1 input signal is high
level (or low level), that input signal is eliminated as noise. If it is sampled three times or more,
the edge is detected as a valid input (n = 0 to 3, 5).
