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.
Since there are two 8bit ports that are read independently,
the interrupt caused by Port 0 will not be cleared by a read
of Port 1, or vice versa.
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.
