*3: Unless the "number of write points" is set to an integral multiple of "column designation", the
column numbers will be random.
*4: Since the last data is always followed by the line feed code, addition normally starts at the
beginning of the new row in the addition mode.
*5: If, in the addition mode, "column designation" is changed from that in the previous writing, the
column numbers are shifted.
