specific data (CSD)
Asks the addressed card to send its card
identification (CID) on CMD-line.
Reads data stream from the card, starting at
the given address, until a
STOP_TRANSMISSION follows.
These Samsung MultiMediaCard do not
support this command
Terminates a read/write stream/multiple
block operation. When CMD12 is used to
terminate a read transaction the card will
respond with R1. When it is used to stop a
write transaction the card will respond with
R1b.
Asks the addressed card to send its status
register.
Sets the card to inactive state in order to
protect the card stack against
communications breakdowns.
Selects a block length (in bytes) for all
following block commands (read and write).
*4
Reads a block of the size selected by the
SET_BLOCKLEN command.
Continuously send blocks of data until
interrupted by a stop.
Writes data stream from the host, starting at
the given address, until a
STOP_TRANSMISSION follows.
These Samsung MultiMediaCard do not
support this command
Defines the number of blocks which are
going to be transferred in the immediatedly
succeeding multiple block read or write
command.
Writes a block of the size selected by the
SET_BLOCKLEN command.
Continuously writes blocks of data until a
STOP_TRANSMISSION follows.
Programming of the card identification
register. This command is only done once
per MultiMediaCard card. The card has
some hardware to prevent this operation
after the first programming. Normally this
command is reserved for the manufacturer.
Programming of the programmable bits of
the CSD.
If the card has write protection features, this
command sets the write protection bit of the
addressed group. The properties of write
protection are coded in the card specific
*2
on CMD-line.
