Universal Platform SOC Processor
Note:
DD (15:0) and HSTROBE signals are shown at both the device and the host to emphasize that cable settling 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.
Figure 25. Sustained Ultra DMA data-out Burst
Note:
1. The device may negate DMARQ to request termination of the Ultra DMA burst no sooner than t
RP
after DDMARDYn is
negated.
2. If the t
SR
timing is not satisfied, the device may receive zero, one, or two more data words from the host.
