Table 5: MII (Diagnosis) Interface Signals

Note: MII diagnosis interface pins are alternatively used as local bus interface or trace pins; in this table the I/O

type is listed for the MII diagnosis function

(2) SMI Interface

The serial management interface (SMI) between MAC and PHY gives access to the PHY’s internal

control registers. There is a common SMI interface for both PHYs; the two PHYs have hardwired

addresses, that are part of the protocol over the SMI interface. The SMI signals can as well be moni-

tored together with the MII signals in MII diagnosis mode.

Table 6 lists the signals that belong to the SMI (diagnosis) interface and the “normal” usage of the

same pins for LBU signals.
