R1b SELECT/DESELECT_CARD Command toggles a card between the
stand-by and transfer states or
between the programming and
disconnect states. In both cases, the
card is selected by its own relative
address and gets deselected by any
other address; address 0 deselects
all.
CMD8 adtc [31–0] stuff bits R1 SEND_EXT_CSD The card sends its EXT_CSD register
as a block of data, with block size of
512 bytes.
CMD9 ac [31–16] RCA
[15–0] stuff bits
R2 SEND_CSD Addressed card sends its
card-specific data (CSD) on the
SD_CMD line.
CMD10 ac [31–16] RCA
[15–0] stuff bits
R2 SEND_CID Addressed card sends its
card-identification (CID) on the
SD_CMD line.
CMD11 adtc [31–0] data address R1 READ_DAT_UNTIL_STOP Reads data stream from the card
starting at the given address until
STOP_TRANSMISSION is received.
CMD12 ac [31–0] stuff bits R1b STOP_TRANSMISSION Forces the card to stop transmission.
CMD13 ac [31–16] RCA
[15–0] stuff bits
R1 SEND_STATUS Addressed card sends its status
register.
CMD14 Reserved
CMD15 ac [31–16] RCA
[15–0] stuff bits
— GO_INACTIVE_STATE Sets the card to inactive state in order
to protect the card stack against
communication breakdowns.
CMD16 ac [31–0] block length R1 SET_BLOCKLEN Sets the block length (in bytes) for all
following block commands (read and
write). Default block length is
specified in the CSD.
CMD17 adtc [31–0] data address R1 READ_SINGLE_BLOCK Reads a block of the size selected by
the SET_BLOCKLEN command.
CMD18 adtc [31–0] data address R1 READ_MULTIPLE_BLOCK Continuously transfers data blocks
from card to host until interrupted by a
stop command.
CMD19 Reserved
CMD20 adtc [31–0] data address R1 WRITE_DAT_UNTIL_STOP Writes data stream from the host
starting at the given address until the
STOP_TRANSMISION command is
received.
CMD21–23 Reserved
