7.2 FEATURES

The most important features and benefits of each Ethernet controller are as follows:
•
Cost-effective connection to an external RIC(Repeater Interface Controller)/Ethernet backbone
•
Buffered DMA (BDMA) engine with burst mode
•
BDMA Tx/Rx Buffers (BTxBUFF and BRxBUFF: 256 bytes/256 bytes)
•
MAC Tx/Rx FIFOs(MTxFIFO and MRxFIFO: 80 bytes/16 bytes) to support re-transmission after collision
without DMA request and DMA latency
•
Data alignment logic
•
Old and new physical media support (compatible with existing 10M-bps networks)
•
100M-bps or 10M-bps operation to allow price/performance options and to support phased conversions
•
Full IEEE 802.3 compatibility for existing applications
•
Media Independent interface (MII) or 7-wire interface
•
Station management (STA) signaling for external physical layer configuration and link negotiation
•
On-chip CAM (21 MAC addresses)
•
Full-duplex mode for doubled bandwidth
•
Hardware support of pause operation for full-duplex flow control
•
Long frame mode for specialized environment
•
Short frame mode for fast testing
•
