5.5 MultiMediaCard Registers
Within the card interface six registers are defined: OCR, CID, CSD, EXT_CSD, RCA and DSR. These can be accessed
only by corresponding commands (see Chapter 6.6). The OCR, CID and CSD registers carry the card/content specific
information, while the RCA and DSR registers are configuration registers storing actual configuration parameters. The
EXT_CSD register carries both, card specific information and actual configuration parameters.
5.5.1 OCR Register
The 32-bit operation conditions register stores the V
DD
voltage profile of the card. In addition, this register includes a sta-
tus information bit. This status bit is set if the card power up procedure has been finished. The OCR register shall be
implemented by all cards.
The supported voltage range is coded as shown in Table , for High Voltage and Dual voltage MultiMediaCards. As long as
the card is busy, the corresponding bit (31) is set to LOW, the ‘wired-and’ operation, described in Chapter 6.1.2 yields
LOW, if at least one card is still busy.
5.5.2 CID Register
The Card IDentification (CID) register is 128 bits wide. It contains the card identification information used during the card
identification phase (MultiMediaCard protocol). Every individual flash or I/O card shall have an unique identification num-
ber. Every type of MultiMediaCard ROM cards (defined by content) shall have an unique identification number.
The structure of the CID register is defined in the following paragraphs:
