(Media Independent Interface) function.

Features of Ethernet Controller are as follows;

• Supports 10 M/100 M Ethernet MAC function compliant to IEEE802.3 and IEEE802.3u

• Supports 3.3 V MII compliant to IEEE802.3u

• Supports full duplex operation for both 100 Mbps and 10 Mbps

• Supports flow control function compliant to IEEE802.3x/D3.2

• Implements 256-Byte FIFO buffer for each Tx and Rx

• Implements address filtering functions for unicast/multicast/broadcast

• Implements MIB counters for network management (MIB II, Ether-like MIB, IEEE802.3LME are supported)

• Implements local DMA controller with individual DMA channels for each Tx and Rx
