The MDIO interface is a simple, two-wire, serial interface, clock and data.
MDIO is used to connect a management entity and a managed PHY for the purposes of controlling the PHY and gathering status from the PHY.
The two lines include the MDC line [Management Data Clock], and the MDIO line [Management Data Input/Output].
The clock is point-to-point [driven by the MAC], while the data line is a bi-directional multi-drop interface.
The data line is Tri-state able and can drive 32 devices. [Tristate Definition]
The clock is defined with a period of 400nS, or a frequency of 2.5MHz. No data on the minimum or maximum pulse rise time.
Data is stable both 10nS before the rising edge of the clock and 10nS after the edge. Data is assumed to be valid at the rising edge.
