The link port data pins, if connected or floated for extended periods (for example, token slave with no token master), do not require pull-ups or pull-downs as there are no
The internal pull-down may not be sufficient. A stronger pull-down may be necessary.

reliability issues and the worst-case power consumption for these floating inputs is negligible. Floating in this case means that these inputs are not driven by any source and
that dc-biased terminations are not present.
