7.2.1
For networking operations the AN983B/BX transmits the data packet from transmit buffers in host memory to
AN983B/BX’s transmit FIFO and receives the data packet from AN983B/BX’s receiving FIFO to receive buffers in
host memory. The descriptors that the AN983B/BX supports to build in host memory are used as the pointers of
these transmit and receive buffers.
There are two structure types for the descriptor, Ring and Chain, supported by the AN983B/BX and are shown
as below. The type selection is controlled by the bit24 of RDES1 and the bit24 of TDES1.
The transmitting and receiving buffers are physically built in host memory. Any buffer can contain either a whole
packet or just parts of a packet. But it can’t contain more than one packet.
