6.3.1 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

6.3.2 Bus Number 1 (Generic)

Through this bus several devices can be handled.

Device Address Size Read Access Write Access

LM86 98h 256 Bytes Yes Yes

SPD EEPROM A0h 256 Bytes Yes No, forbidden

6.3.3 BusNumber 2 (JILI)

The JILI EEPROM refers to the LCD/LVDS interface. It contains the panel specific timing parameters (e.g. a

DisplayID

record).

Device Address Size Read Access Write Access

JILI EEPROM A0h 512 Bytes Yes Yes
