Display
The capacity checked is displayed in units of 64KB.
UP-S04MB Check
4096KB:PASS!!(or ERROR!!)

The error address and bit are displayed only when an error occurs
(They are not displayed if there is no error.)
How to exit the program
You can exit the program by pressing the CANCEL key after the
results are displayed.
2)-4. Standard ROM Check
Checking
The standard ROM area (200000H - 3FFFFFH) is added in units
of bytes. When the lowest 2 digits of the result is 20H, it is re-
garded as normal.
In addition, the ROM version and model name code stored in the
addresses 31FFE0H - 31FFFFH where the ROM version and
checksum correction data are stored are displayed. Data (ASCII)
is stored in the following formats:
31FFE0H~31FFEFH : Model name CODE (Example: "UP-600",
to be displayed until DATA becomes 00H.)
31FFF0H~31FFF9H : 27801R****(****=PROGRAM VERSION)
31FFFAH~31FFFBH : BLOCK NO.("20"~"3F")
31FFFCH : TERMINATOR ("=")
31FFFDH~31FFFEH : BLOCK VERSION (Example: "00")
31FFFFH : CHECK SUM correction DATA
FLASH ROM used as the standard ROM has 64K-byte-unit re-
write BLOCKs. To perform VERSION management in the BLOCK
unit, these BLOCKs have the same 16 byte organization as those
after the previous 31FFF0H and arranged every 64KBYTE. At this
time, the checksum for each BLOCK is corrected to be 01H so
that the entire 2MBYTE become a total of 20H.
Regarding the display of the PROGRAM VERSION, the FLASH
write MASTER EPROM has 8Mbits chips to allow management of
the block units of the chip. The PROGRAM VERSION stored in
blocks at 21H and 31H are displayed.
0 PAGE (BLOCK) where the IPL is stored, displays the PRO-
GRAM VERSION of the IPL to make it possible to manage individ-
ual programs.

2)-5. SERVICE ROM Check
Checking
The SERVICE ROM area composed of two EPROMs (D00000H -
EFFFFFH) is added in units of bytes for each chip. If the lowest 2
digits are 10H, it is regarded as normal.
In addition, the ROM version and model name code stored in the
addresses D1FFE0H - D1FFFFH where the ROM version and
checksum correction data are stored are displayed. Data (ASCII)
is stored in the following formats:
D1FFE0H~D1FFEFH : Model name CODE(Example: "UP-600",
to be displayed until data is 00H.)
D1FFF0H~D1FFF9H : 27801R****(****=PROGRAM VERSION)
D1FFFAH~D1FFFBH : BLOCK NO.("20"~"2F")
D1FFFCH : TERMINATOR("=")
D1FFFDH~D1FFFEH : BLOCK VERSION(Example:"00")
D1FFFFH : CHECK SUM correction DATA
This SERVICE ROM is used to write data into FLASH ROM and if
any error occurs during rewriting of the FLASH ROM, it is not
possible to resume operations. Its configuration is the same as the
standard ROM.
0 PAGE (BLOCK) where the IPL is stored displays the PRO-
GRAM VERSION of the IPL to make it possible to manage individ-
ual programs.
