contain the selection or
reselection IDs. These two 8-bit registers contain the SCSI
ID that the chip responds to on the SCSI bus. Each bit
represents one possible ID; the most significant bit of
represents ID 15, and the
least significant bit of RESPID0 represents 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 RESPID1
and RESPID0 registers. However, the chip can arbitrate
with only one ID value in the
register.
