Values
Max
t0 is the minimum total cycle time, t2 is the
minimum command active time, and t2i is
the minimum command recovery time or
command inactive time. The actual cycle
time equals the sum of the actual command
active time and the actual command inactive
time. The three timing requirements of t0,
t2, t2i shall be met. The minimum total
cycle time requirement, t0, is greater than
the sum of t2 and t2i. This means host
implementation
can lengthen either or both t2 and t2i. to
ensure that t0 is equal to the value reported
in the devices identify drive data. A device
implementation shall support any legal host
implementation.
