3.12.6 Transmit Examples
3.12.6.1 TX Example 1
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:
 7-Byte “Data Start Offset”
 79-Bytes of payload data
 16-Byte “Buffer End Alignment”
Buffer 1:
 0-Byte “Data Start Offset”
 15-Bytes of payload data
 16-Byte “Buffer End Alignment”
Buffer 2:
 10-Byte “Data Start Offset”
 17-Bytes of payload data
 16-Byte “Buffer End Alignment”
