Example:
When the BASE ADDRESS parameter contains the value 0
these outputs have addresses 0, 1, 2, 3 respectively, and
in this case, if the ADDRESS input equals 2 the VALUE will
be copied to the third output.
If a second block is being used, 8 outputs can be
demultiplexed by putting the value 4 as the BASE
ADDRESS in the second block and connecting the
VALIDATION and ADDRESS inputs to the same source.
