* @brief Ethernet Media Access Controller/Management Data Input/Output.
*
* The EMAC controls the flow of packet data from the system to the PHY. The MDIO module controls PHY
* configuration and status monitoring.
*
* Both the EMAC and the MDIO modules interface to the system core through a custom interface that
* allows efficient data transmission and reception. This custom interface is referred to as the EMAC control
* module and is considered integral to the EMAC/MDIO peripheral
