CHAPTER 21 INTERRUPT SERVICING/EXCEPTION PROCESSING FUNCTION
An example of the timing of noise elimination performed by the timer T input pin digital filter is shown Figure 21-15.

Remark
If the noise elimination clock cycle is sampled twice or less while the INTP3 input signal is high
level (or low level), the input signal is judged as noise and eliminated. If the noise elimination
clock cycle is sampled three times or more, the edge of the signal is detected as a valid input.
