Extension Connector J12

The I/O extension connector provides cost-effective, flexible configuration options. To provide
flexible configuration of additional low speed PC devices, e.g. Super I/O, or CAN controller, the
LPC port is connected to the I/O extension connector. The I/O extension interface contains all
the signals necessary to connect up to two LPC devices.
