SCSI Operating Registers
If the SCSI clock doubler is enabled, use the desired
frequency after doubling to determine the conversion
factor.

When this bit is set, the LSI53C875 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 initiator mode as a result of being
reselected.
SRE
Enable Response to Selection
5
When this bit is set, the LSI53C875 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 are used to store the LSI53C875 encoded
SCSI ID. This is the ID which the chip asserts when
arbitrating for the SCSI bus. The IDs that the LSI3C875
responds to when being selected or reselected are
configured in the
and
registers. The priority of
the 16 possible IDs, in descending order is:
