The order of RELATED DIMMER, RELATED PIP, RELATED TOUCH PANEL and others is determined according to frequency of changing.
*
When a writing & reading error or data check (checksum, magnitude relation) error occurs, initialization is done with data belonging to the software at the error time, and initialization is performed
per divided section described above.
However, RELATED DIMMER should be further divided into sections such as address 00H
∼
02H and 03H
∼
04H, then initialized.
*
The user changeable parts (address 00H
∼
02H) in the segment RELATED DIMMER is not a target of checksum.
*
Concerning the segment RELATED DIMMER, considering PIP register configuration, data obtained from PIP can be stored without software processing.
And the alignment is designed to send data obtained from EEPROM to PIP without processing it. (same as NN629)
Each area is divided according as whether it is changed during operation or not. (Checksum division is carried out to each.)
*
Address 2H, remote control reverse output DC center value reference is not a target of checksum because it maintains default settings, and basically it is READ ONLY and is not shipped.
*
Address 40H, sampling phase reference is not a target of checksum because it maintains default settings, and basically it is READ ONLY and is not shipped.
*
At the time of EEPROM reset, the address above (excluding 2AH, 40H) is initialized with data belonging to the software.
*
A : Microcomputer writes the result whether flicker adjustment is performed or not (direct mode, EEPROM adjustment screen).
*
B : Production engineering jig: After completing EEPROM adjustment, the value is written (this value is displayed on the confirmation screen).
