	tDVS	70	-	48	-	30	-	20	-	6	-	Data valid setup time at	ns
												sender (from data valid until
												STROBE edge) (see Note 4).
	tDVH	6	-	6	-	6	-	6	-	6	-	Data valid hold time at sender	ns
												(from STROBE edge until
												data may become invalid)
												(see Note 4).
	tFS	0	230	0	200	0	170	0	130	0	120	First STROBE time (for	ns
												device to first negate
												DSTROBE from STOP during
												a data-in burst).
	tLI	0	150	0	150	0	150	0	100	0	100	Limited interlock time (see	ns
												Note 3).
	tMLI	20	-	20	-	20	-	20	-	20	-	Interlock time with minimum	ns
												(see Note 3).
	tUI	0	-	0	-	0	-	0	-	0	-	Unlimited interlock time (see	ns
												Note 3).
	tAZ	-	10	-	10	-	10	-	10	-	10	Maximum time allowed for	ns
												output drivers to release
												(from asserted or negated).
	tZAH	20	-	20	-	20	-	20	-	20	-	Minimum delay time required	ns
												for output.
	tZAD	0	-	0	-	0	-	0	-	0	-	Drivers to assert or negate	ns
												(from released).
	tENV	20	70	20	70	20	70	20	55	20	55	Envelope time (from DMACK-	ns
												to STOP and HDMARDY-
												during data-in burst initiation,
												and from DMACK to STOP
												during data-out burst
												initiation).
	tSR	-	50	-	30	-	20	-	NA	-	NA	STROBE to DMARDY- time	ns
												(if DMARDY- is negated
												before this long after
												STROBE edge, the recipient
												receives no more than one
												additional data word).
	tRFS	-	75	-	70	-	60	-	60	-	60	Ready-to-final STROBE time	ns
												(no STROBE edges are sent
												this long after negation of
												DMARDY-).
	tRP	160	-	125	-	100	-	100		100	-	Minimum time to assert STOP	ns
												or negate DMARQ.
	tIORDYZ	-	20	-	20	-	20	-	20	-	20	Maximum time before	ns
												releasing IORDY.
	tZIORDY	0	-	0	-	0	-	0	-	0	-	Minimum time before driving	ns
												STROBE (see note 5).
	tACK	20	-	20	-	20	-	20	-	20	-	Setup and hold times for	ns
												DMACK- (before assertion or
												negation).
