Configure the SD rate pre-emphasis
pulse width on trace driver output1
(DDO1).
Range: 0 to 15d.
Adjust the pre-emphasis pulse width to
better match the channel loss response
shape.
Note: By default, the trace driver SD
settings are applied for all rates (see
CTRL_OUTPUT1_TRDR_PER_RATE for
per rate setting).
