INT: Interrupt Output
The opendrain interrupt output is activated when one of
the port pins configured as an input changes state (differs
from the corresponding input port register bit state). The
interrupt is deactivated when the input returns to its previous
state or the input port register is read. Changing an I/O from
an output to an input may cause a false interrupt if the state
of the pin does not match the contents of the input port
register.
