1) Standard RAM Check
1
Check content
For the SRAM of the standard 2MB RAM, the following test is per-
formed. The memory contents will not be changed by this check.
The following processes are performed for the memory address
(600000H~7FFFFFH) to be checked.
In case of a compare error in the check sequences of
PASS1~PASS6, an error display is displayed. If there is no error at
all, the check is terminated normally.
In addition, the following address check is performed.
In case of an error, an error is made and read/write of the address
where the error occurred is repeated.
2
Display
The error address and the bit are displayed only when an error
occurs. (If the error does not occur, the error address will not be dis-
played.)

Terminating procedure
After completion of the test, press the Touch panel.
2) UP-S02MB2 Check
1
Check content
The UP-S02MB2 presence check is performed in the following pro-
cedure. The memory contents will not be changed by this check.
• 55AAH is written into 9FFFFEH.
• 9FFFFEH is read at the time of the synchronous command of E
clock and compared with 55AAH. If both data are correct, the fol-
lowing procedure is performed. If not, "Extended RAM size: 0KB"
is displayed and the test is terminated.
The following processes are performed for the check address
(800000H~9FFFFFH).

In addition, the following address check is performed in the above
test sequence.

1) Standard ROM Check

Details of checking
Perform the following checks on each 1Mbyte in the standard ROM
area (200000H - 5FFFFFH).
For the area "200000H - 2FFFFFH", read the character string
stored in the address "21FFF0H - 21FFF5H". If it reads "27801R"
or "sample", add the area "200000H - 2FFFFFH" to the byte unit. If
the lower 2 digits are 10H as a result of the addition, the area is
regarded as normal. Perform the same check on the areas after
300000H. If the lower 2 digits are not 10H as a result of the addi-
tion, the error message is displayed. If the character string is not
"27801R" or "sample", it is regarded that any program is not stored
in the areas after that area and the sum check is terminated.
For the area "300000H - 3FFFFFH", read the character string
stored in the address "31FFF0H - 31FFF5H". If it reads "27801R"
or "sample", add the area "300000H - 3FFFFFH" to the byte unit to
check whether it is normal or not.
Perform the same check on the areas "400000H - 4FFFFFH" and
"500000H - 5FFFFFH".
If there is no errors when the sum check is finished, the message
"Standard ROM Sum Check: PASS!!" appears.
The ROM version and model code stored in the address "21FFE0H
- 31FFFFH" are also displayed.
The formats of data (ASCII) stored are as follows:

"Standard ROM Sum Check: PASS!!" appears.

The formats of data (ASCII) stored are as follows:
The Flash ROM, used as the standard ROM, has 64-Kbyte unit
rewrite blocks. To control the version in blocks, it is organized in
the same 16-byte configuration as those after the aforementioned
21FFF0H and arranged for each 64 Kbyte. At this time, the sum of
each block is corrected to become 01H and thus the sum of the
entire 1 Mbyte becomes 10H.
The master EPROM (8 Mbits) for writing Flash ROM consists of 4
chips. To make it possible to control the program version by the
chip, the program version stored in the blocks 21H, 31H, 41H and
51H are displayed. If the beginning of each ROM version stored in
the blocks 21H, 31H, 41H and 51H is not "27801R" or "sample", it
is regarded that the area does not have any program stored, and
thus no program version is displayed.
In addition, the 0 PAGE (Block) where IPL is stored shows the pro-
gram version of IPL so that it can control programs individually.
