High pass DLL value

This command is typically used for debug or characterization of the controller to DMD interface.

The return data is specified by the read parameter data.

DMD I/F training tests/calibrates the DLL that is associated with each contoller pin pair, trying each of the DLL parameter values (0 to 50), looking for a pass (‘0’) or fail (‘1’) response for each value. Thus, the full training profile for each pin pair is made up of a 51 bit pass/fail result. This result is provided on full profile bits 50:0.

The full profile response has a region of passing DLL values. The highest DLL value for this region is returned as the high pass DLL value, the smallest DLL value is returned as the low pass DLL value, and the algorithm selected value as the selected DLL value.

This command does not run the DMD I/F training algorithm. This is done automatically by the system. This command returns the result from the most recent training event.
