7.7 PCI Bus Masters

The conga-XLX supports four external PCI Bus Masters. There are no limitations in
connecting bus master PCI devices.
Note
If there are two devices connected to the same PCI REQ/GNT pair and they are
transferring data at the same time then the latency time of these shared PCI devices
can not be guaranteed.
7.8 I²C Bus
There are no onboard resources connected to the I²C bus. Address 16h is reserved for
congatec Battery Management solutions.

7.9 SM Bus

System Management (SM) bus signals are connected to the AMD Geode™ CS5536
companion device and the SM bus is not intended to be used by off-board non-system
management devices. For more information about this subject contact congatec
technical support.

7.10 LPC Bus

Low Pin Count bus signals are connected to the AMD Geode™ CS5536 companion
device and are available on the X2 connector of the XTX module. The LPC bus can be
used to interface an off-board non-system LPC device like a Super I/O. There is only
the configuration base address 4Eh/4Fh available to access an off-board LPC devices.
