Port direction register
INTiIC register
Comparator Bi can use the same digital filter as the INTi input. The sampling clock can be selected by bits
INTiF1 and INTiF0 in the INTF register. The INTiCOUT signal output from comparator Bi is sampled every
sampling clock. When the level matches three times, the IR bit in the INTiIC register is set to 1 (interrupt
requested).
Figure 30.3 shows a Configuration of Comparator Bi Digital Filter, and Figure 30.4 shows an Operating
Example of Comparator Bi Digital Filter.
