Register: 0x0A (0x8A)
SCSI Selector ID (SSID)
Read Only
VAL SCSI Valid Bit 7
If VAL is asserted, then the two SCSI IDs are detected
on the bus during a bus-initiated selection or reselection,
and the encoded destination SCSI ID bits below are valid.
If VAL is deasserted, only one ID is present and the
contents of the encoded destination ID are meaningless.
R Reserved [6:3]
ENID[2:0] Encoded Destination SCSI ID [2:0]
Reading the SSID register immediately after the
LSI53C810A has been selected or reselected returns the
binary-encoded SCSI ID of the device that performed the
operation. These bits are invalid for targets that are
selected under the single initiator option of the SCSI-1
specification. This condition can be detected by
examining the VAL bit above.
