Description
The transfer request signal from the target to the initiator in the
SCSI information transfer phases.
The input signal is used as a timing control signal in the data trans-
fer sequence. Active “H” signal.
Response signal from the initiator to the target in response to the
REQ signal in the SCSI information transfer phases.
The input signal is used as a timing control signal in the data trans-
fer sequence.
Active “H” signal.
Indicates that the initiator has a message for the target.
Active “H” signal.
Specifies the type of information being transferred on the SCSI
data bus.
Active high signal which becomes “H” when the message phase is
specified.
Specifies the type of information being transferred on the SCSI
data bus.
Active high signal which becomes “H” during the command, status,
and message phases.
Specifies a type of information transferred on the SCSI data bus,
indicative of data transfer direction.
Active high signal which is “H” when data is transferred from target
to initiator. When “L”, data is transferred from initiator to target.
Indicates that the SCSI bus is being used. Also in function as a bus
usage right acquisition request signal in the arbitration phase.
Use the output signal as a control signal for the external differential
driver/receiver.
Active “H” signal.
The output signal used by the initiator and target during the selec-
tion phase (when the initiator selects the target) or
reselection phase (when the target reselects the initiator) and the
input signal used to detect the opposing output signal.
Use the output signal as a control signal for the external differential
driver/receiver.
Active “H” signal.
The output signal used to instruct a reset for another SCSI bus de-
vice or the reset input signal from another SCSI bus device.
Use the output signal as a control signal for the external differential
driver/receiver.
Active “H” signal.
