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 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.
