Pin Function
MII Management (MIIM) Interface: Data I/O
This pin requires an external 4.7K pull-up resistor.
MII Management (MIIM) Interface: Clock Input
This pin is synchronous to the MDIO data line.
MII Mode: Receive Data Output[3]
Configuration Mode: The pull-up/pull-down value is latched as PHYADDR[1]
during reset. See “Strapping Options” section for details.
MII Mode: MII Receive Data Output[2]
Configuration Mode: The pull-up/pull-down value is latched as PHYADDR[2]
during reset. See “Strapping Options” section for details.
MII Mode: Receive Data Output[1]
RMII Mode: Receive Data Output[1]
Configuration Mode: The pull-up/pull-down value is latched as PHYADDR[3]
during reset. See “Strapping Options” section for details.
MII Mode: Receive Data Output[0]
RMII Mode: Receive Data Output[0]
SMII Mode: Receive Data and Control
Configuration Mode: The pull-up/pull-down value is latched as PHYADDR[4]
during reset. See “Strapping Options” section for details.
3.3V digital VDD
Ground
