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.
*6
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
data (WP_GRP_SIZE).
If the card provides write protection
features, this command clears the write
protection bit of the addressed group.
If the card provides write protection
features, this command asks the card to
send the status of the write protection bits.
