The S/PDIF connector is an audio interface for transmitting digital audio signals. The system
includes an S/PDIF header on the board.
LPC Connector
The Low Pin Count Interface was defined by Intel
®
Corporation to facilitate the industry’s transition
towards legacy free systems. It allows the integration of low-bandwidth legacy I/O components
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 embedded controller
solutions. Data transfer on the LPC bus is implemented over a 4 bit serialized data interface, which
uses a 24MHz LPC bus clock. For more information about LPC bus, please refer to the Intel
®
Low
Pin Count Interface Specification Revision 1.1. The table below indicates the pin assignments of
the LPC connector.
