Internal I/O Connectors
The LAN LED connector is used to detect the connection state of RJ45 LAN ports when the
connection is made to an active network via a cable. The pin functions of the LAN LED connec-
tor are listed below.

The Low Pin Count Interface was defined by Intel
®
Corporation to facilitate the industry’s transi-
tion towards legacy free systems. It allows the integration of low-bandwidth legacy I/O compo-
nents within the system, which are typically provided by a Super I/O controller. Furthermore, it
can be used to interface firmware hubs, Trusted Platform Module (TPM) devices and embed-
ded controller solutions. Data transfer on the LPC bus is implemented over a 4 bit serialized
data interface, which uses a 33MHz LPC bus clock. For more information about LPC bus, refer
to the Intel
®
Low Pin Count Interface Specification Revision 1.1’. Pin assignments of the LPC
connector are listed in the table below.
