4.4.2.7 Transmit Examples
4.4.2.7.1 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 bytes Data Start Offset
• 499 bytes of payload data
Buffer 1:
• 0 byte Data Start Offset
• 503 bytes of payload data
Buffer 2:
• 2 bytes Data Start Offset
• 62 bytes of payload data
Table 4-6 illustrates the TX Command structure for this example, and also shows how data is passed to the TX data
FIFO.
