DSP COM.
This item shows a detail of the communication check result between
each LSI and microcomputer.
004H: communication error between RC LSI and microcomputer
002H: communication error between PR LSI and microcomputer
001H: communication error between PP LSI and microcomputer
n
The RC LSI performs the data communication to a microcomputer with the
following six signals:
Pin 26: CSPin 23: SDA1
Pin 25: SCK Pin 22: SDA2
Pin 24: SDA0 Pin 21: SDA3
The PR LSI performs the data communication to a microcomputer with the
following six signals:
Pin 58: CSPin 55: SDA1
Pin 57: SCK Pin 54: SDA2
Pin 56: SDA0 Pin 53: SDA3
The PP LSI performs the data communication to a microcomputer with the
following six signals:
Pin 41: CSPin 38: SDA1
Pin 40: SCK Pin 37: SDA2
Pin 39: SDA0 Pin 36: SDA3
If an error is detected during the data communication with LSI, other error
item may be detected at the same time.
MEMORY
This item shows a detail of the communication check result between
each EEPROM and microcomputer.
080H: communication error between EEPROM (IC103) on the ES
board and microcomputer
040H: communication error between EEPROM (IC301) on the DPR
board and microcomputer
020H: communication error between EEPROM (IC1) on the TG
board and microcomputer
010H: communication error between EEPROM (IC504) on the AT
board and microcomputer
n
When the back up data is used because of an error in EEPROM on the TG,
DPR, and ES boards, and when the micro computer's standard value is used
because of an error in EEPROM on the AT board, indication of each
EEPROM on the service menu will show a blank.
