0 I2C (primary) JIDA 1
1 SMBus Generic 2
2 I2C JILI 1 Not supported on Basic variant
11.3.1 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 per-
formed above a defined address.
Device Address Size Read Access Write Access
JIDA EEPROM A0h 512 Bytes Yes
Yes, between
28h to 1C8h
11.3.2 Bus Number 1 (Generic)
Through this bus several devices can be handled.
Note: The accelerometer is not available before hardware revision 3.0 (only
Plus variant).
Device Address Size Read Access Write Access
Accelerometer 6Eh 32 Bytes Yes Yes
Temp. sensor 98h 256 Bytes Yes Yes
SPD EEPROM A0h 256 Bytes Yes No, forbidden
11.3.3 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
