Residue Information:
The Valid bit will be set. The information bytes will be as follows:
The requested transfer length (in bytes).
The difference (in blocks) between the requested transfer size and the actual number of
blocks transferred. A partially transferred block is not counted, so for example, if 3.5
out of 10 blocks have been transferred the residue will be 7.
If the last block is an illegal length block, it is not counted among those transferred. For
example, if 4 legal length blocks and 1 illegal length block have been transferred out
of a total of 10, the residue will be 6.
