1 Flash ATA cards are formatted in the quick format mode (the
file allocation table and directory information in the root
directory are cleared). For an unformatted flash ATA card,
format it with a personal computer.
2 Files on a memory card that can be displayed and selected
are the first 64 files registered in the root directory area.
3 On a flash memory card, a particular file cannot be erased.
File erasure must be performed for the entire card at a time.
Therefore, the following operations cannot be performed:
S Deletion of already existing files
S Overwrite of a file having the same name
4 When data is written to a flash memory card, the last 128KB
area of the flash memory card itself is used as a buffer area.
This reduces the usable capacity of the flash memory card
by 128KB.
5 Only the root directory area can be used to display, read,
and write files on a memory card. The subdirectory area
cannot be used. File names on the memory card must each
consist of up to eight uppercase alphanumeric characters,
and extensions must each consist of up to three uppercase
alphanumeric characters.
6 The time required to read or write data varies depending on
the type and use status of the memory card.
7 When a memory card is used, files on the memory card may
be erased by mistake. So, necessary data should be
backed up on the personal computer.
53 Other supported functions
For functions that supported the use of SRAM memory cards and
