... When writing to the internal registers with a "load mode" operation, the specific address is required. This requires the controller to know if the rank is mirrored or not. This requires a fewrules. Mirroring is done on 2 rank modules and can only be done on the second rank. There is not a requirement that the second rank be mirrored ...
