TX Example 1
Transmit Examples
In this example a single, 111-Byte Ethernet packet will be transmitted. This packet is divided into three
buffers. The three buffers are as follows:
Buffer 0:
■
■
■
Buffer 1:
■
■
■
Buffer 2:

Note 4.15 The following figure illustrates the TX command structure for this example, and also shows
7-Byte “Data Start Offset”
79-Bytes of payload data
16-Byte “Buffer End Alignment”
0-Byte “Data Start Offset”
15-Bytes of payload data
16-Byte “Buffer End Alignment”
10-Byte “Data Start Offset”
17-Bytes of payload data
16-Byte “Buffer End Alignment”
how data is passed to the TX data FIFO.
