5.10 Ethernet Media Access Controller
The Ethernet Media Access Controller (EMAC) provides an efficient interface between RM4x and the
network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps
in either half- or full-duplex mode, with hardware flow control and quality of service (QoS) support.
The EMAC controls the flow of packet data from the RM4x device to the PHY. The MDIO module controls
PHY configuration and status monitoring.
Both the EMAC and the MDIO modules interface to the RM4x device 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. The control module is also used to
multiplex and control interrupts.
