30 | The MDIO (Management Data Input/Output) protocol decoder supports the | |
31 | MII Management serial bus (a bidirectional bus between the PHY and the STA), | |
32 | with a clock line (MDC) and a bi-directional data line (MDIO). | |
33 | ||
34 | MDIO is also known as SMI (Serial Management Interface). | |
35 | ||
36 | It's part of the Ethernet standard. | |
