ferred in a payload format via the data lines. The last (least significant) bit of the protection bits corresponds to the first addressed
group. If the addresses of the last groups are outside the valid range, then the corresponding write protection bits shall be set to zero.

Defines the number of blocks which are going
to be transferred in the immediately succeeding
multiple block read or write command.
If the argument is all 0s, the subsequent read/
write operation will be open-ended.
Writes a block of the size selected by the
SET_BLOCKLEN command.
Continuously writes blocks of data until a
STOP_TRANSMISSION follows or the
requested number of block received.
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 pro-
tection 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.
