4.5.3 Relative Card Address (RCA)
The 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 to 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 in Standby State with the command SELECT_DESELECT_CARD (CMD7). The RCA is
programmed with the command SET_RELATIVE_ADDRESS (CMD3) during the initialization
procedure. The content of this register is lost after power down. The default value is assigned when an
internal reset is applied by the power up detection unit of the MultiMediaCard.
4.5.4 Card Specific Data (CSD)
The card specific data register describes how to access the card content. The CSD defines card
operating parameters like maximum data access time, data transfer speed.
