MDIO Registers
The specification calls for up to 64 registers to be supported by MDIO. Some registers must be included
to meet the minimum MDIO specification; they are identified as the basic register set. Other registers are
optional and are considered part of the extended register set. The MC92604 has two sets of MDIO registers
(one per transceiver channel). Registers for address 0–6 and 15–18, as defined in the standard
specification, are fully supported. Registers 7–14 and 19–31 are not supported in the MC92604. The
MDIO registers are identified in Table 4-1.
