5.6 How to design the Ethernet interface
The NXP i.MX6UL Ethernet Media Access Controller (MAC) is designed to support both 10 and 100 Mbps Ethernet/IEEE standard
802.3™ networks. The 10-Mbps and 100-Mbps RMII Ethernet physical interfaces is supported. In the figure is shown how to connect
the Ethernet interface to module.
