Definition:
EOF = 0
EOF = 0
EOF = 1
In the example shown in
MAC starts the frame by acquiring the medium and transmitting the preamble. Then, the
fragments 0, 1, 2 are transmitted in order for a total of 446 bytes (39 + 388 + 19). Since the
CRC bit in the first frame fragment is clear, the HW appends the 4 byte CRC. Thus, 4 more
bytes are added to the frame for the CRC making the total frame length 450 bytes. Finally, the
MAC sends the end-of-frame.
The CMD field is 4 bits. Only the AF bit is valid. The other fields are reserved.

Example: Fragments 0, 1, 2 make-up one complete frame.
