Description
automatic MDS start-up
width of MDS (in output clock periods)
Description
Description
lockout detector soft reset
lock detector soft reset
relock mode
Description
number of evaluation cycles applied for MDS.
lock mode
number of succeeding 'equal' detections until lock
delay offset for dataflow (two’s complement [16 to 15]
no mds_win/mds_ref generation in advance
mds_win/mds_ref run-in before mds_evaluation
