When asserted high—the 8B/10B encoder
encodes the data on the tx_datain port as
a /Kx.y/ control code group.
When de-asserted low—it encodes the data
on the tx_datain port as a /Dx.y/ data code
group.

When asserted high—forces the 8B/10B
encoder to encode the data on the
tx_datain port with a positive or negative
disparity depending on the tx_dispval
signal level.
When de-asserted low—the 8B/10B encoder
encodes the data on the tx_datain port
according to the 8B/10B running disparity
rules.

A high level—when the tx_forcedisp
signal is asserted high, it forces the 8B/10B
encoder to encode the data on the
tx_datain port with a negative starting
running disparity.
A low level—when the tx_forcedisp
signal is asserted high, it forces the 8B/10B
encoder to encode the data on the
tx_datain port with a positive starting
running disparity.
Channel Width:
8—tx_dispval = 1
16—tx_dispval = 2
