CMDRSP [127:0] Command Response
The Table below describes the mapping of command responses from
the SD Bus to this register for each response type. In the table, R[]
refers to a bit range within the response data as transmitted on the SD
Bus, REP[] refers to a bit range within the Response register.
128-bit Response bit order : {RSPREG3, RSPREG2, RSPREG1,
RSPREG0}
