Table 14 lists the pin signal definitions when a port is operating in the MDI
configuration at 10 or 100 Mbps.
Table 15 lists the pin signal definitions when a port is operating in the MDI-
X configuration at 10 or 100 Mbps.
The MDI/MDI-X setting is established automatically when a port is set to
Auto-Negotiation. If a port’s speed and duplex are set manually, the MDI/
MDI-X setting defaults to the MDI-X setting.
