Local SMB Devices
The CC3-CAJUN contains a few devices that are reachable via the System Management Bus
(SMB). These are the clock generation chip, the SPD EEPROM on the SO-DIMM memory module
and a CPU temperature controlling device in particular. Other devices could be connected to the
SMB via the CompactPCI signals IPMB SCL (J1 B17) and IPMB SDA (J1 C17).
