Controls the DQ mapping compensation applied for CRC calculation. For each nibble of the DQ bus, the DIMM SPD defines a DQ Map Index to define the bit connectivity to each rank. Program the DQ Map Index retrieved from the SPD for each nibble into the corresponding register in the DMC for correct CRC operation. Access restrictions: RO Can be read from when in ALL states. Cannot be written to and only updated when in CONFIG, LOW-POWER or PAUSED states.
