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 KSZ8864RMN is assigned as “0x2” for port 1, “0x3” for
port 2. The “REGAD” supported are 0x0-0x5 (0h-5h), 0x1D (1dh) and 0x1F (1fh).
