REGISTER DESCRIPTION
The 78Q2120 implements ten 16-bit registers which are accessible via the MDIO and MDC pins. The supported
registers are shown below. Unsupported registers will be read as all zeros. All of the registers respond to the
broadcast address, PHYAD value 00000.
The MII management 16-bit register set implemented in the 78Q2120 is as follows:
