INT pin specification
When condition watching mode, INT output pin works for reporting of detection of watching port.
(a) When command D6=0(including default time after RESET release)
INT pin falls when detection of watching port is received. And INT pin rises after ACK-output which is on the I

In the case that there is a change in detection ports once, and there are another changes before returning the ACK (as
shown “A term”), then watching data is saved. And the output data in this case will be “AND” output of every bits of the
watching data.
