¯¯¯ : Interrupt Output
The open-drain 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

cause a false interrupt if the state of the pin does not
match the contents of the input port register.
