4.1.14
LPC Bus Interface
The Low Pin Count (LPC) interface signals are connected to the AMD Fusion
Controller Hub. The LPC low-speed interface can be used for peripheral
circuits. For example, it can be used as an external super I/O controller to
combine legacy-device support into a single IC. The implementation of this
subsystem complies with the COM Express
TM
specification. For additional
implementation information, refer to the PICMG COM Express® Design Guide on
the PICMG website.
