Programmable Pre-Emphasis
The programmable pre-emphasis module controls the output driver to
boost the high frequency components, to compensate for losses in the
transmission medium, as shown in
dynamically or statically set. There are five possible pre-emphasis
settings (1 through 5), with 5 being the highest and 0 being no
pre-emphasis.
