5.4.2.7 Transmit Examples
5.4.2.7.1
TX Example 1
In this example a single, 1064-Byte Ethernet frame will be transmitted. This packet is divided into three buffers. The
three buffers are as follows:
Buffer 0:
• 3-Byte “Data Start Offset”
• 499-Bytes of payload data
Buffer 1:
• 0-Byte “Data Start Offset”
• 503-Bytes of payload data
Buffer 2:
• 2-Byte “Data Start Offset”
• 62-Bytes of payload data
FIGURE 5-6: TX Example 1 on page 52 illustrates the TX command structure for this example, and also shows how
data is passed to the TX data FIFO.
