MII Management (MIIM) Registers
The MIIM interface is used to access the MII PHY registers defined in this section. The SPI, I2C and SMI 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. When the switch is in “center side media converter mode”. only PHY
port 1 is accessible after the PHYAD is programmed via the SPI, I2C or SMI interface.
