(37) Transmit REQ assertion period with P_CRCA transitioning
The minimum time that a target shall assert the REQ signal during a DT DATA phase while
transitioning P_CRCA with pCRC protection enabled.
Specified to provide the increased receive REQ assertion period, subject to loss on the
interconnect.
(38) Transmit REQ negation period with P_CRCA transitioning
The minimum time that a target shall negate the REQ signal during a DT DATA phase while
transitioning P_CRCA with pCRC protection enabled.
Specified to provide the increased receive REQ negation period, subject to loss on the
interconnect.
(39) QAS arbitration delay
The minimum time a SCSI device with QAS enabled (see 1.6.2.2) shall wait from the detection of
the MSG, C/D, and I/O signals being false to start QAS until the DATA BUS is examined to see if
QAS has been won (see 1.6.2.2).
(40) QAS assertion delay
The maximum time allowed for a SCSI device to assert certain signals during QAS.
(41) QAS release delay
The maximum time allowed for a SCSI device to release certain signals during QAS.
(42) QAS non-DATA phase REQ(ACK) period
The minimum time a QAS-capable SCSI INIT port shall ensure the REQ and ACK signals are
asserted and that data is valid during COMMAND, MESSAGE, and STATUS phases.
(43) Residual skew error
The maximum timing error between the deskewed data and REQ or ACK internal to the receiving
SCSI device after skew compensation.
