The command address argument was out
of the allowed range for this card.

ADDRESS_

ERX
’0’= no error
’1’= error
A multiple block or stream read/write
operation is (although started in a valid
C
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.
30
ADDRESS_MISALIGN
’0’= no error
’1’= error
A multiple block read/write operation
(although started with a valid
C
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
29
BLOCK_LEN_ERROR
’0’= no error
’1’= error
the previously defined block length is
illegal for the current command (e.g. the
host issues a write command, the current
C
block length is smaller than the maximum
allowed value for the card and it is not
allowed to write partial blocks)
28
ERASE_SEQ_ERROR
’0’= no error
’1’= error
An error in the sequence of erase
commands occurred.

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.
