When writing to register 26,
be sure to preserve the values
of these bits. Changes to these
values can interrupt the normal
operation of the SFP module.
All voltages measured peak-to-
peak into a 100-ohm load.
Output amplitude values are
approximate.

When writing to register 27,
be sure to preserve the values
of these bits. Changes to these
values can interrupt the normal
operation of the SFP module.
If enabled, BASE-X link will
come up after 200 ms even if
BASE-X auto-negotiation fails.
