The J3 connector provides access to the Ethernet ports 0 and 1. This connector uses IEC 61000-
4-2-rated TVS components to help protect against ESD damage. The Ethernet controller auto-
detects 10BaseT/100Base-TX connectors.
Figure 24 shows the location and pin orientation of the Ethernet connector.
