Seed value for PRBS generation. It can be used for polynomial
seed or as the actual data depending on the value of
PRBS_MODE in
Note: The polynomial seed must be set to a non-zero value in
order for the PRBS generator to work as intended. In addition, at

polynomial and index 0 must be set to 1 to guarantee proper
pseudo-random generation.
