(8)
Cable skew
The maximum difference in propagation time allowed between any two SCSI bus signals measured
between any two SCSI devices excluding any signal distortion skew delays.
(9)
Data release delay
The maximum time for an initiator to release the DATA BUS, DB(P_CRCA), DB(P1) signals
following the transition of the I/O signal from false to true.
(10)
DIFFSENS voltage filter time
The minimum time DIFFSENS voltage shall be sensed continuously within the voltage range of a
valid SCSI bus mode.
(11)
Physical Disconnection delay
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.
(12)
Power on to selection
The recommended maximum time from power application until a SCSI target is able to respond
with appropriate status and sense data to the TEST UNIT READY, INQUIRY, and REQUEST
SENSE commands (See SCSI-3 Primary Commands Standard.)
(13)
Reset delay
The minimum time that the RST signal shall be continuously true before the SCSI device shall
initiate a reset.
(14)
Reset hold time
The minimum time that the RST signal is asserted. There is no maximum time.
(15)
Reset to selection
The recommended maximum time from after a reset condition until a SCSI target is able to
respond with appropriate status and sense data to the TEST UNIT READY, INQUIRY, and
REQUEST SENSE commands (See SCSI-3 Primary Commands Standard).
(16)
Selection abort time
The maximum time that SCSI device shall take from its most recent detection of being selected or
reselected until asserting the BSY signal in response. This time-out is required to ensure that a
target or initiator does not assert the BSY signal after a SELECTION or RESELECTION phase
has been aborted.
(17)
Selection time-out delay
The minimum time that an initiator or target should wait for a assertion of the BSY signal during
the SELECTION or RESELECTION phase before starting the time-out procedure. Note that this
is only a recommended time period.
