SCSI Wide Residue
[7:0]
After a wide SCSI data receive operation, this register
contains a residual data byte if the last byte received was
never sent across the DMA bus. It represents either the
first data byte of a subsequent data transfer, a residue
byte which should be cleared when an Ignore Wide
Residue message is received, or an overrun data byte.
The power-up value of this register is indeterminate.
