Figure 73.  Triple-Speed Ethernet Software Driver Architecture

Notes to Triple-Speed Ethernet Software Driver Architecture:

  1. The first n bytes are reserved for SGDMA descriptors, where n = (Total number of descriptors + 3) × 32. Applications must not use this memory region.
  2. For MAC variations without internal FIFO buffers, the transmit and receive FIFOs are external to the MAC function.
