MII Management (MIIM) Registers
The MIIM interface is used to access the MII PHY registers defined in this section. The SPI, I
interfaces can also be used to access these registers. The latter three interfaces use a different mapping
mechanism than the MIIM interface.
As defined in the IEEE 802.3 specification, the “PHYAD” are assigned as “0x1” for PHY port 1 and “0x2” for PHY
port 2. The “REGAD” supported are 0,1,2,3,4, and 5.
