TX Command 'A'
Buffer End Alignment = 0
Data Start Offset = 6
First Segment = 1
Last Segment = 1
Buffer Size =183
TX Command 'B'
Packet Length = 183
TX Example 2
In this example, a single 183-Byte Ethernet packet will be transmitted. This packet is in a single buffer
as follows:
Figure 3.15, "TX Example 2" illustrates the TX command structure for this example, and also shows
how data is passed to the TX data FIFO. Note that the packet resides in a single TX Buffer, therefore
both the FS and LS bits are set in TX command ‘A’.
