Description
These bits are cleared to H'00 by writing an arbitrary
value.
RSPR0 to RSPR16 comprise a continuous 17-byte shift
register.
Description
Reserved
These bits are always read as 0. The write value should
always be 0.
CRC status
[Clearing condition]
When writing any value to these bits, cleared to 00000.
CRC status is stored. CRC status is command
response from the card when data is written into the
MMC card.
