Notes:
1) CONTRAST data
The CONTRAST data is adjustable, and used as reference data for other adjustment items,
which is not memorized in the EEPROM.
2) SUB BRI R and SUB BRI B data
The displayed value or EEPROM written data is different from the setting value for the 2-screen
IC register (TC90A64F : IC1).
(Before displayed on the screen, the setting value is converted via some software.)

It's because the settings are adjustable by the user.
