5.6.3.3 Sustained Ultra DMA data in burst

5.6.3.2 contains the values for the timings for each of the Ultra DMA Modes.

Note:

to emphasize that cable setting time as well as cable propagation delay shall
not allow the data signals to be considered stable at the host until some time
after they are driven by the device.
