ETHERNET CONTROLLER
The MC68EN302, like the MC68360 QUICC, provides full duplex Ethernet along with
multiprotocol support on the SCC channels. On the MC68EN302, the Ethernet controller is
independent of the CPM and therefore the MC68EN302 provides the Ethernet channel in
addition to the pre-existing 302 SCC channels without sacrificing any SCC pins. The
Ethernet controller consists of an 802.3/Ethernet MAC layer protocol machine with an
internal CAM, transmit and receive FIFOs, buffer descriptor memory and a dual channel
DMA controller. The buffer descriptor memory, CAM and DMA controller all interface to the
module bus. A block diagram of the Ethernet controller is shown in Figure 4-1.
Features are:
802.3 Ethernet compliant MAC layer (1-10 Mbps) with industry standard interface
Full-duplex operation
128 byte transmit and receive FIFOs
Collision retry does not generate extra bus bandwidth
Collision fragments automatically discarded
64 entry CAM with optional hash mode
Buffer descriptor memory on-chip
