Enable Response to Reselection

When this bit is set, the LSI53C896 SCSI function is
enabled to respond to bus-initiated reselection at the chip
ID in the
and
registers. Note that the
chip does not automatically reconfigure itself to the
initiator mode as a result of being reselected.
SRE
Enable Response to Selection
5
When this bit is set, the LSI53C896 SCSI function is able
to respond to bus-initiated selection at the chip ID in the
and
registers. Note that the
chip does not automatically reconfigure itself to target
mode as a result of being selected.

Encoded Chip SCSI ID
[3:0]
These bits store the LSI53C896 SCSI function encoded
SCSI ID. This is the ID that the chip asserts when
arbitrating for the SCSI bus. The IDs that the LSI53C896
SCSI function responds to when selected or reselected
are configured in the
and
registers. The priority of
the 16 possible IDs, in descending order is:
