MII Port Status Pins
Four signaling pins (MII_LNK_STA#, MII_SPD_STA, MII_DUP_STA, MII_FCTRL_STA) are used to provide operating
status to the MII port MAC in real time after reset. This means the external MAC or PHY must be forced to the same port
status as the MII port. The MII port automatically detects the link status both from the TXC of the external PHY and
MII_LNK_STA#.

Note 1: Pulled high or floating sets the speed to 100Mbps. Pulled down sets the speed to 10Mbps.
Note 2: Pulled high or floating enables full duplex. Pulled down sets half duplex.
Note 3: Pulled high or floating enables flow control or backpressure. Pulled down disables flow control or backpressure.
