Fast Ethernet Controller (FEC)
The descriptor controller is a RISC-based controller providing these functions in the FEC:
The RAM is the focal point of all data flow in the Fast Ethernet controller and divides into transmit and
receive FIFOs. The FIFO boundaries are programmable using the FRSR register. User data flows to/from
the DMA block from/to the receive/transmit FIFOs. Transmit data flows from the transmit FIFO into the
transmit block, and receive data flows from the receive block into the receive FIFO.
