IR bit in
INTiIC register
The INTi input contains a digital filter. The sampling clock is selected using bits INTiF1 and INTiF0 in register
INTF. The INTi level is sampled every sampling clock cycle and if the sampled input level matches three times,
the IR bit in the INTiIC register is set to 1 (interrupt requested).
Figure 11.9 shows the INTi Input Filter Configuration. Figure 11.10 shows an Operating Example of INTi Input
Filter.
