Description
Continuously writes blocks of data
until a STOP_TRANSMISSION
follows or the requested number of
blocks has been received.
Programming of the card identification
register. This command must be
issued only once per card. The card
contains hardware to prevent this
operation after the first programming.
Normally this command is reserved
for manufacturer.
Programming of the programmable
bits of the CSD.
Description
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.
Description
Sets the address of the first erase
group within a range to be selected
for erase.
Sets the address of the last erase
group within a continuous range to be
selected for erase.
