General Description of Checking Method
2. Version
(2-2) Revision
ROM revision number is displayed.
Error: Not detected.
The revision number defined in the source file of ROM
(IC106 or 107) is displayed with four digits.
(2-3) ROM Check Sum
Check sum is calculated.
Error: Not detected.
8-bit data are added up to the ROM (IC106 or 107) address
0x000F0000 to 0x002EFFFF, and the result is displayed
with 4-digit hexadecimal number. Error is not detected.
Compare the result with the specified value.
(2-4) Model Type
Model code is displayed.
Error: Not detected.
The model code read from the EEPROM is displayed with
2-digit hexadecimal number.
(2-5) Region
Region code is displayed.
Error: Not detected.
The region code determined from the model code is dis-
played.
(2-6) M't check
Mount resistance is checked.
Error 22: The region code does not accord.
Check wether the region code that is deduced from model
resistance and destination resistance accords with the re-
gion code that is deduced from region resistance value.
3. Peripheral
(3-2) EEPROM Check
Data write 
→ read, and accord check
Error 03: EEPROM write/read discord.
0x9249, 0x2942 and 0x4294 are written to the address 0x00
to 0xFF of the EEPROM and then read for checking. Be-
fore writing, the data are saved, then after checking, they
are written to restore the contents of EEPROM.
(3-3) –––––––
Check no support.
(3-4) –––––––
Check no support.
(3-5) –––––––
Check no support.
(3-6) VENC Check
Data write 
→ read, and accord check
Error 52: Write and read data discord.
Accessing to the SYSCON may be defective.
(3-7) –––––––
Check no support.
(3-8) EX RAM Check
Test Data write 
→ read, and accord check
Error 02: The external RAM used in the system control is
checked.
4. Servo
(4-2) Servo DSP Check
Data write 
→ read, and accord check
Error 12: Read data discord
0x9249, 0x2942 and 0x4294 are written to the RAM ad-
dress 0x602 of the Servo DSP and then read for checking.
(4-3) –––––––
Check no support.
(4-4) RF Amp (SSI) W/R Check
Date write 
→ read and accord check
Error 13: RF Amp resister write, and read data discord
Implement 8-bit shift operation of the 0x01 to the read-
able/writable register of the RF Amp. If once write data do
not accord with read data, it is NG.
