(1) t 0 is the minimum total cycle time, t 2 is the minimum command active time, and t 2i 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, t 2 , and t 2i shall be met. the minimum total cycle time requirement is greater than the sum of t 2 and t 2i . this means a host implementation can lengthen either or both t 2 or t 2i to ensure that t 0 is equal to or greater than the value reported in the device?s identify device data. (2) this parameter specifies the time from the negation edge of -iord to the time that the data bus is released by the device. (3) the delay from the activation of -iord or -iowr until the state of iordy is first sampled. if iordy is inactive then the host shall wait until iordy is active before the pio cycle can be completed. if the device is not driving iordy negated at t a after the activation of -iord or -iowr, then t 5 shall be met and t rd is not applicable. if the device is driving iordy negated at the time t a after the activation of -iord or -iowr, then t rd shall be met and t5 is not applicable. (4) t 7 and t 8 apply only to modes 0, 1 and 2. for other modes, this signal is not valid. (5) iordy is not supported in this mode.

(4) the negation of iordy by the device is used to extend the pio cycle. the determination of whether the cycle is to be extended is made by the host after t a from the assertion of -iord or -iowr. the assertion and negation of iordy is described in the following three cases: (4-1) device never negates iordy: no wait is generated. (4-2) device starts to drive iordy low before t a , but causes iordy to be asserted before t a : no wait generated. (4-3) device drives iordy low before t a : wait generated. the cycle completes after iordy is reasserted. for cycles where a wait is generated and -iord is assert ed, the device shall place read data on d15-d00 for t rd before causing iordy to be asserted.
