Section 24 Multimedia Card Interface (MMCIF)
• All cards are initialized to the idle state by CMD0.
• The operation condition registers (OCR) of all cards are read via wired-OR and cards that
• The card identifications (CID) of all cards in the ready state are read via wired-OR by CMD2.
• A relative address (RCA) is given to the card in the acknowledge state by CMD3.
• By repeating CMD2 and CMD3, RCAs are given to all cards in the ready state to make them

CMD7, CMD9, CMD10, CMD13, CMD15, CMD39, and CMD55 are relative address commands
that address the card by RCA. The relative address commands are used to read card administration
information and original information, and to change the specific card states.
CMD7 sets one addressed card to the transfer state, and the other cards to the standby state. Only
the card in the transfer state can execute flash-memory operation commands, other than broadcast
or relative-address commands.
(3)
Some broadcast commands do not require a command response.
Figure 24.3 shows an example of the command sequence for commands that do not require a
command response.
Figure 24.4 shows the operational flow for commands that do not require a command response.
• Make settings to issue the command.
• Set the START bit in CMDSTRT to 1 to start command transmission. MCCMD must be kept
• The end of the command sequence is detected by poling the BUSY flag in CSTR or by the

The cards that are not deactivated enter the ready state.
Each card compares it's CID and data on the MCCMD, and if they are different, the card aborts
the CID output. Only one card in which the CID can be entirely output enters the acknowledge
state. When the R2 response is necessary, set CTOCR to H'01.
