Time
The minimum time that an SCSI device shall wait from
its detection of the BUS FREE phase (BSY and SEL both
false for a bus settle delay) until its assertion of BSY
when going to the ARBITRATION phase
The maximum time for an SCSI device to assert BSY and
its SCSI ID bit on the DATA BUS after it detects BUS
FREE phase (BSY and SEL both false for a bus settle
delay) for the purpose of entering the ARBITRATION
phase
The minimum time to wait for the bus to settle after
changing certain control signals as called out in the
protocol definitions
The maximum difference in propagation time allowed
between any two SCSI bus signals measured between
any two SCSI devices
The maximum time for an initiator to release the DATA
BUS signals following the transition of the I/O signal
from false to true
The minimum time required for deskew of certain
signals
The minimum time that a target shall wait after
releasing BSY before participating in an ARBITRATION
phase when honoring a DISCONNECT message from the
initiator
The minimum time added between the assertion of REQ
(or REQB) or ACK (or ACKB) and the changing of the
data lines to provide hold time in the initiator or target
while using synchronous data transfers. REQB and
ACKB timings only apply to optional wide data
transfers.
The minimum time that a target shall negate REQ (or
REQB) while using synchronous data transfers. Also,
the minimum time that an initiator shall negate ACK (or
ACKB) while using synchronous data transfers. REQB
and ACKB timings only apply to optional wide data
transfers.
The recommended maximum time from power
application until an SCSI target is able to respond with
appropriate status and sense data to the TEST UNIT
READY, INQUIRY, and REQUEST SENSE commands
