43    Glue devices have a variable number of big endian <<output>>
47    Writing to an output register results in an event being driven
49    corresponding output port.
51    Reading an <<output>> register returns either the last value
58    <<glue>>: In addition to driving its output interrupt port with any
60    corresponding <<output>> register.  Such input interrupts, however,
61    are not propogated to an output interrupt port.
64    and then both stored in <<output>> register zero and propogated to
65    output interrupt output port zero.
88    int[0..] (input, output)
90    Both an input and an output port.
103    output interrupt ports.
