Do the UniPHY-based memory controllers support Short ZQ Calibration?

Description

No, the UniPHY-based memory controllers do not support Short ZQ Calibration. The UniPHY-based controllers use DQS Tracking to adjust for small voltage and temperature variations. Refer to the Functional Description - UniPHY (.PDF) chapter of the External Memory Interface Handbook for more details on DQS Tracking.
