Card Identification (CID)
This register contains the card identification information used during the card identification procedure. It is
a 128 bit wide register, one-time programmable by the provider. The CID is divided into eight slices:

The CID has to be error free. To ensure the correctness of the CID, a 7-bit CRC checksum is added to the
end of the CID. The CRC7 is computed according to chapter “Cyclic Redundancy Check (CRC)”.
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 these Hitachi MultiMediaCards, or when the command
GO_IDLE_STATE (CMD0) is detected by these Hitachi MultiMediaCards.
