Minimum time from -IORDY high to -IORD high is 0 nsec, but minimum -IORD width shall still be met. (1) 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.

This means a host implementation can lengthen either or both t2 or t2i to ensure that t0 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 tA after the activation of -IORD or -IOWR, then t5 shall be met and tRD is not applicable.

For other modes, this signal is ignored. (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 tA 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 tA, but causes IORDY to be asserted before tA: No wait generated. (4-3) Device drives IORDY low before tA: wait generated. The cycle completes after IORDY is reasserted. For cycles where a wait is generated and -IORD is asserted, the device shall place read data on D15-D00 for tRD before causing IORDY to be asserted.

When this protocol is enabled, the Ultra DMA protocol shall be used instead of the Multiword DMA protocol when these commands are issued by the host.

Several signal lines are redefined to provide different functions during an Ultra DMA data burst. These lines assume their UDMA definitions when: 1. An Ultra DMA mode is selected, and 2. A host issues a READ DMA, or a WRITE DMA command requiring data transfer, and 3. The device asserts (-)DMARQ, and 4. The host asserts (-)DMACK. These signal lines revert back to the definitions used for non-Ultra DMA transfers upon the negation of -DMACK by the host at the termination of an Ultra DMA data burst. With the Ultra DMA protocol, the STROBE signal that latches data from D[15:00] is generated by the same agent (either host or device) that drives the data onto the bus. Ownership of D[15:00] and this data strobe signal are given either to the device during an Ultra DMA data-in burst or to the host for an Ultra Transcend Information Inc. 10 Ver 1.0 TTrraannsscceenndd 4444--P Piinn IID DE E FFllaasshh M Moodduullee ((H Hoorriizzoonnttaall)) TTS S112288M M ~~ 44G GD DO OM M4444H H--S S DMA data-out burst. During an Ultra DMA data burst a sender shall always drive data onto the bus, and, after a sufficient time to allow for propagation delay, cable settling, and setup time, the sender shall generate a STROBE edge to latch the data. Both edges of STROBE are used for data transfers so that the frequency of STROBE is limited to the same frequency as the data. Words in the IDENTIFY DEVICE data indicate support of the Ultra DMA feature and the Ultra DMA modes the device is capable of supporting. The Set transfer mode subcommand in the SET FEATURES command shall be used by a host to select the Ultra DMA mode at which the system operates. The Ultra DMA mode selected by a host shall be less than or equal to the fastest mode of which the device is capable. Only one Ultra DMA mode shall be selected at any given time. All timing requirements for a selected Ultra DMA mode shall be satisfied. Devices supporting any Ultra DMA mode shall also support all slower Ultra DMA modes. An Ultra DMA capable device shall retain the previously selected Ultra DMA mode after executing a software reset sequence or the sequence caused by receipt of a DEVICE RESET command if a SET FEATURES disable reverting to defaults command has been issued. The device may revert to a Multiword DMA mode if a SET FEATURES enable reverting to default has been issued. An Ultra DMA capable device shall clear any previously selected Ultra DMA mode and revert to the default non-Ultra DMA modes after executing a power-on or hardware reset. Both the host and device perform a CRC function during an Ultra DMA data burst. At the end of an Ultra DMA data burst the host sends its CRC data to the device. The device compares its CRC data to the data sent from the host. If the two values do not match, the device reports an error in the error register. If an error occurs during one or more Ultra DMA data bursts for any one command, the device shall report the first error that occurred. If the device detects that a CRC error has occurred before data transfer for the command is complete, the device may complete the transfer and report the error or abort the command and report the error. NOTE − If a data transfer is terminated before completion, the assertion of INTRQ should be passed through to the host software driver regardless of whether all data requested by the command has been transferred.
