register, and then to the SCSI bus. The SODR buffer
register is not used for asynchronous transfers. It is
possible to use this bit to determine how many bytes
reside in the chip when an error occurs.
AIP
Arbitration in Progress
4
Arbitration in Progress (AIP = 1) indicates that the
LSI53C896 SCSI function has detected a Bus Free
condition, asserted SBSY, and asserted its SCSI ID onto
the SCSI bus.
LOA
Lost Arbitration
3
When set, LOA indicates that the LSI53C896 SCSI
function has detected a bus free condition, arbitrated for
the SCSI bus, and lost arbitration due to another SCSI
device asserting the SSEL/ signal.
WOA
Won Arbitration
2
When set, WOA indicates that the LSI53C896 SCSI
function has detected a Bus Free condition, arbitrated for
the SCSI bus, and won arbitration. The arbitration mode
selected in the
register
must be full arbitration and selection to set this bit.
RST
SCSI RST/ Signal
1
This bit reports the current status of the SCSI RST/
signal, and the RST signal (bit 3) in the
register. This bit is not
latched and may change as it is read.
SDP0
SCSI SDP0 Parity Signal
0
This bit represents the present state of the SCSI SDP0/
parity signal. This signal is not latched and may change
as it is read.
