4.3.3.7 Ethernet 10/100 (EMAC) Port
Except for SAM9G15, the processor has two 10/100 Mbps Ethernet Mac Controllers.
The EK board is equipped with two Davicom DM9161AEP PHYs for each Ethernet port. Both PHY
Transceivers are configured as RMII mode. Both PHY transceivers have an RJ45 port with embedded
transformer and three-status LEDs.
By default, the ETH0 interface is implemented on the EK board. Additionally, for monitoring and control
purposes, an LED functionality is carried on the RJ45 connectors to indicate activity, link, and speed sta-
tus information for the respective ports.
