Registers
In the case of a SCSI data receive, if there is a byte in
the
register then this
address points to the location where that byte must be
stored. The SWIDE byte must be manually written to
memory and this address must be incremented prior to
updating any scatter/gather entry.
In the case of a SCSI data receive, if there is not a byte
in the SWIDE register then this address is the next
location that should be written to when this I/O restarts.
No manual flushing will be necessary.
In the case of a SCSI data send, all data sent to the SCSI
bus will be accounted for and any data left in the part is
ignored and is automatically cleared from the FIFOs.

Direct BMOV:
In the case of a direct BMOV, this register contains
the address the BMOV was fetched from when the
phase mismatch occurred.
Indirect BMOV:
In the case of an indirect BMOV, this register contains
the address the BMOV was fetched from when the
phase mismatch occurred.
Table Indirect BMOV:
In the case of a Table Indirect BMOV, this register
contains the address of the Table Indirect entry being
used when the phase mismatch occurred.
