If an external 10BASE-T ENDEC is being used, the MII multiplexer routes the internal MII lines to the
10Base-T Module. The I/O multiplexer connects the output of the module to the output pins.
Figure 7. Transmit and Receive Data Paths
Similarly, the receive data path flows through the appropriate modules, routed by the I/O multiplexer.
The MII multiplexer then connects the appropriate module outputs to the receive function. The receive
function performs the Ethernet MAC operations.
The MII Interface
The W110 communicates with external PHY devices through the logical MII interface. The logical MII is
divided into two signal sets. One set handles data transmission and reception while the second set handles
MII management functions.
Figure 8. MII Data and Management Signal Sets
Within the W110, the data function are handled by the TFUN and RFUN modules. The MII management
set is handled by the MII module. Host access to the management interface is on a word basis through the
normal host interface. The interface between the MII and the external PHY is a clocked serial interface as
defined in the IEEE 802.3u standard.
