of the last groups are outside the valid range, then the corresponding write protection bits shall

Command description
command is an application specific
command rather than a standard
command.
These Renesas 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 Renesas MultiMediaCards
do not support this command.
Reads the OCR register of a card.
‘1’ in the CRC option bit will turn the
