Fast Ethernet Controller (FEC)
The descriptor controller is a RISC-based controller that provides the following functions in the
FEC:
19-2
• Initialization (those internal registers not initialized by the user or hardware)
• High level control of the DMA channels (initiating DMA transfers)
• Interpreting buffer descriptors
• Address recognition for receive frames
• Random number generation for transmit collision backoff timer
