The S3C4510B has an ethernet controller which operates at either 100-Mbits or 10-Mbits per second in halfduplex
or full-duplex mode. In half-duplex mode, the controller supports the IEEE 802.3 carrier sense multiple
access with collision detection (CSMA/CD) protocol. In full-duplex mode, it supports the IEEE 802.3 MAC control
layer, including the pause operation for flow control.……………………
