    Nothing has to be unlinked to not send data.  It is entirely
    possible to have things linked and not data flowing.  You can drop
    data manually with a pad probe, or you could change the element
    states to not have them producing data.  It all depends on what your
    exact requirements and elements involved are.<br>
