Sets parameter "LD" for SF detection.
LD defines the threshold of the number of errors that are detected in the ND frame
as SF detection condition.
MD[7:0]

Sets parameter "MD" for SF detection.
MD defines the number of consecutive events as SF detection condition, in each of
which LD or more errors are detected in one frame to be monitored (successive ND
frames).
