Basic Commands (class 0) and Read Stream Command (class 1)
CMD
index Type Argument
Resp Abbreviation
Command description
CMD0 bc [31:0] stuff bits 
GO_IDLE_STATE Resets all cards to Idle State
CMD1 bcr [31:0] OCR
R3
without busy
SEND_OP_COND
Checks for cards not supporting the
full range of 2.0 V to 3.6 V. After
receiving CMD1 the card sends an R3
response (refer to Chapter
“Responses”).
CMD2 bcr [31:0] stuff bits R2
ALL_SEND_CID
Asks all cards in ready state to send
their CID*¹ numbers on CMD-line
CMD3 ac
[31:16] RCA
R1
[15:0] stuff bits
SET_RELATIVE_A Assigns relative address to the card in
DDR
identification state.
CMD4 bc
[31:16] DSR

[15:0] stuff bits
SET_DSR
Programs the DSR of all cards in
stand-by state.
CMD7 ac
[31:16] RCA
[15:0] stuff bits
R1b (only SELECT/
Command toggles a card between the
the
DESELECT_CARD standby and transfer states or between
selected
the programming and disconnect state.
card)
In both cases the card is selected by
its own relative address while
deselecting the prior selected card.
Address 0 deselects all.
CMD9 ac
[31:16] RCA
R2
[15:0] stuff bits
SEND_CSD
Asks the addressed card to send its
card-specific data (CSD)*² on CMD-
line.
CMD10 ac
[31:16] RCA
R2
[15:0] stuff bits
SEND_CID
Asks the addressed card to send its
card identification (CID) on CMD-line.
CMD11 adtc [31:0] data
R1
READ_DAT_UNTIL Reads data stream from the card,
address
_STOP

STOP_TRANSMISSION follows.
CMD12 ac
[31:0] stuff bits R1b*³
STOP_TRANSMISS Forces the card to stop transmission
ION
CMD13 ac
[31:16] RCA
R1
[15:0] stuff bits
SEND_STATUS
Asks the addressed card to send its
status register.
CMD15 ac
[31:16] RCA


GO_INACTIVE_ST Sets the card to inactive state in order
ATE
to protect the card stack against
communications breakdowns.
Notes: 1. CID register consists of 128 bits (starting with MSB, it is preceded by an additional start bit, ends
with an end bit)
2. CSD register consists of 128 bits (starting with MSB, it is preceded by an additional start bit,
ends with an end bit)
3. This command is indicating the busy status of the MultiMediaCard via the data channel.
