if the Offset is not compatible with the size of the EF (Offset > EF size), the processing state returned is ′6B00′,
if the size of the data to be written is not compatible with the size of the EF [F3(Offset + Lc > EF size)] the processing state returned is ′6700′,
if an integrity error is detected within the file attributes, the card shall consider the file as corrupted and unrecoverable, the processing state returned is ′6400′ or ′6500′,
