5.6.3.8 Sustained Ultra DMA data out burst

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

Note:

DD (15:0) and HSTROBE signals are shown at both the device and the host to emphasize that
cable setting time as well as cable propagation delay shall not allow the data signals to be
considered stable at the device until some time after they are driven by the host.
