5.7 Ethernet (FEC) Interface
The signals from the MCU’s Fast Ethernet Controller are terminated to Mother Board interface
connector, J501. Further these signals are connected with Ethernet Physical Interface in the Mother
Board. Also, in order to support Reduced Media-Independent Interface (RMII) mode, the Daughter
