9.1. Core Overview
The Intel® Management Data Input/Output (MDIO) IP core is a two-wire standard management interface that implements a standardized method to access the external Ethernet PHY device management registers for configuration and management purposes. The MDIO IP core is IEEE 802.3 standard compliant.
To access each PHY device, the PHY register address must be written to the register space followed by the transaction data. The PHY register addresses are mapped in the MDIO core’s register space and can be accessed by the host processor via the Avalon® Memory-Mapped ( Avalon® -MM) interface. This IP core can also be used with the Intel FPGA 10-Gbps Ethernet MAC and Intel FPGA Triple Speed Ethernet IP Core to realize a fully manageable system.
