4. Relative Card Address Register (RCA)
The writable 16-bit relative card address register carries the card address assigned by the host during the card
identification. This address is used for the addressed host-card communication after the card identification procedure.
The default value of the RCA register is 0x0001. The value 0x0000 is reserved to set all cards into the Stand-by State
with CMD7. In SD mode, the value of this register is generated by random number generator inside the card. Please
reference to SD specification for detail information.
5. Card Specific Data Register (CSD)
The Card-Specific Data register provides information on how to access the card contents. The CSD defines the data
format, error correction type, maximum data access time, data transfer speed, whether the DSR register can be used
etc. The programmable part of the register can be changed by CMD27.
