MII Data Interface
The Media Independent Interface (MII) is compliant with the IEEE 802.3 Specification. It provides a common interface
between MII PHYs and MACs, and has the following key characteristics:
Pin count is 15 pins (6 pins for data transmission, 7 pins for data reception, and 2 pins for carrier and collision
indication).
10Mbps and 100Mbps data rates are supported at both half and full duplex.
Data transmission and reception are independent and belong to separate signal groups.
Transmit data and receive data are each 4-bit wide, a nibble.
By default, the KSZ8051MLL is configured to MII mode after it is powered up or hardware reset with the following:
A 25MHz crystal connected to XI, XO (pins 15, 14), or an external 25MHz clock source (oscillator) connected to
XI.
The CONFIG[2:0] strapping pins (pins 27, 41, 40) set to ‘000’ (default setting).
