What is MDIO?

MDIO (Management Data Input/Output) is a serial interface used to access control and status registers within a PHY (physical layer) chip. It's commonly used in Ethernet applications to configure and monitor the PHY, allowing a host system to manage link speed, duplex mode, and other PHY-related parameters. It is a two-wire interface consisting of MDC (Management Data Clock) and MDIO (Management Data Input/Output).
