Data Transfer Mode
When in Standby State, both CMD and DAT lines are in the push-pull mode. As long as the content of all
CSD registers is not known, the f
PP
clock rate is equal to the slow f
OD
clock rate. SEND_CSD (CMD9)
allows the host to get the Card Specific Data (CSD register), e.g. ECC type, block length, card storage
capacity, maximum clock rate etc..

MultiMediaCard State Diagram
(Data Transfer Mode)
The command SELECT_DESELECT_CARD (CMD7) is used to select one card and place it in the
Transfer State. If a previously selected card is in the Transfer State its connection with the host is released
and it will move back to the Stand-by State. Only one card can be, at any time, in the Transfer State. A
selected card is responding the CMD7, the deselected one does not respond to this command. When
CMD7 is sent including the reserved relative card address 0x0000, all cards transfer back to Stand-by State.
This command is used to identify new cards without resetting other already acquired cards. Cards to which
an RCA has already been assigned, do not respond to the identification command flow in this state. All the
data communication in the Data Transfer Mode is consequently a point-to point communication between
the host and the selected card (using addressed commands). All addressed commands are acknowledged by
a response on the CMD line. All read commands (data is sent from the card via data lines) can be
interrupted at any time, by a stop command. The data transfer will terminate and the card will stop or start
working on the next command. The DAT bus line signal level is high when no data is transmitted. A
transmitted data block consists of a start bit (LOW), followed by a continuous data stream. The data stream
contains the net payload data (and error correction bits if an off-card ECC is used). The data stream ends
