7.3.1 Bus Number 0 (JIDA)
This bus allows access to the JIDA EEPROM in which KONTRON specific manufacturing parameters are
stored. A damage of these parameters leads to a loss of warranty. Due to this a write cycle may only be
performed above a defined address.
Device Address Size Read Access Write Access
JIDA EEPROM A0h 512 Bytes Yes No, forbidden
7.3.2 Bus Number 1 (Generic)
Through this bus several devices can be handled.
Device Address Size Read Access Write Access
GPIO Control 30h 34 Bytes Yes Yes
SPD EEPROM A0h 256 Bytes Yes No, forbidden
7.3.3 BusNumber 2 (JILI)
The JILI EEPROM refers to the LCD/LVDS interface. It contains the panel specific timing parameters (e.g. a
DisplayID
TM record).
Device Address Size Read Access Write Access
JILI EEPROM A0h 512 Bytes Yes Yes
