Answer The interrupt pin on the HT49RU80 is shared with a Port B I/O pin. On the interface card the exact labeling for this pin should be PB0/INT0 and PB1/INT1, however the actual marking only quotes PB0 and PB1 without mentioning int. Users should take not of this point as it may lead to user misunderstandings.
