MIIM Registers
All the registers defined in this section can be also accessed via the SPI interface. Note: different mapping mechanisms
used for MIIM and SPI. The “PHYAD” defined in IEEE is assigned as “0x1” for port 1, “0x2” for port 2, “0x3” for port 3,
“0x4” for port 4, and “0x5” for port 5. The “REGAD” supported are 0, 1, 2, 3, 4, 5.
