A timing example of noise elimination performed by the timer T input pin digital filter is shown Figure 9-2.
Noise elimination clock
Remark
Internal signal
Input signal
If there are two or fewer noise elimination clocks while the TIT00, TIT01, TENC01, TECR0, and
EVTT00 input signals are high level (or low level), the input signal is eliminated as noise. If it is
sampled three times or more, the edge is detected as a valid input.
