selection or reselection IDs. In other words, these two
8-bit registers contain the ID that the chip responds to on
the SCSI bus. Each bit represents one possible ID with
the most significant bit of
representing ID 15 and the least significant bit of
RESPID0 representing ID 0. The
register still contains the chip ID used during arbitration.
The chip can respond to more than one ID because more
than one bit can be set in the
