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

Command description
Used to set/reset the password or
lock/unlock the card. The structure
of the data block is described in
chapter “Card lock/unlock
operation”. The size of the Data
Block is defined by the
SET_BLOCK_LEN command.
command is an application specific
command rather than a standard
command.
These Hitachi MultiMediaCards do
not support this command.
Used either to transfer a data block
to the card or to get a data block
from the card for general purpose /
application specific commands. The
size of the data block shall be set by
the SET_GLOCK_LEN command.
These Hitachi MultiMediaCards do
not support this command.
Reads the OCR register of a card.
‘1’ in the CRC option bit will turn the
