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:

DD (15:0) and DSTROBE signals are shown at both the host and the device 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.
