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, and t2i shall be met. The minimum total cycle time
requirements are greater than the sum of t2 and t2i. This means a host
implementation may lengthen either or both t2 or t2i to ensure that t0 is
equal to or greater than the value reported in the devices IDENTIFY
