12.6.2.3 Quadlet Transmit
Three quadlet transmit formats are shown below. In these figures: The first quadlet contains packet control information. The second and third
quadlets contain 16-bit destination ID and either the 48-bit quadlet-aligned destination offset (for requests) or the response code (for responses).
The fourth quadlet contains the quadlet data for read response and write quadlet request formats, or the upper 16 bits contain the data length
for the block read request format.
