Bit Name Description Access Reset
20 ce_reduction_volume_addr_and_change 
Device supports CE pin reduction with volume assignments,volume addressing 
                 and volume change command sequence.For any device configured by host to be used in 
                 volume addressing mode, this bit must be set to 1.
