MII Management (MIIM) Registers
The MIIM interface is used to access the MII PHY registers defined in this section. The SPI, I
also be used to access some of these registers. The latter three interfaces use a different mapping mechanism than the
MIIM interface.
The “PHYADs” by defaults are assigned “0x1” for PHY1 (port 1) and “0x2” for PHY2 (port 2). Additionally, these
“PHYADs” can be programmed to the PHY addresses specified in bits[7:3] of Register 15 (0x0F): Global Control 13.
The “REGAD” supported are 0x0-0x5, 0x1D and 0x1F.
