Command description
Selects a block length (in bytes) for all
following block commands (read and
write).*
Reads a block of the size selected by
the SET_BLOCKLEN command.*
Continuously send blocks of data until
interrupted by a stop.
Command description
writes data stream from the host,
starting at the given address, until a
STOP_TRANSMISSION follows.
Command description
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.
