Description
The command address argument was out
of the allowed range for this card.
A multiple block or stream read/write
operation is (although started in a valid
address) attempting to read or write
beyond the card capacity.
The commands address argument (in
accordance with the currently set block
length) positions the first data block
misaligned to the card physical blocks.
A multiple block read/write operation
(although started with a valid
address/block-length combination) is
attempting to read or write a data block
which is not aligned with the physical
blocks of the card.
Either the argument of a
SET_BLOCKLEN command exceeds the
maximum value allowed for the card, or
the previously defined block length is
illegal for the current command (e.g. the
host issues a write command, the current
block length is smaller than the maximum
allowed value for the card and it is not
allowed to write partial blocks)
An error in the sequence of erase
commands occurred.
An invalid selection of erase groups for
erase occurred.
Attempt to program a write-protected
block.
When set, signals that the card is locked
by the host
Set when a sequence or password error
has been detected in lock/unlock card
command
The CRC check of the previous command
failed.
Command not legal for the card state
Card internal ECC was applied but failed
to correct the data.
(Undefined by the standard) A card error
occurred, which is not related to the host
command.
