When burst mode is selected on the DRAM interface, the DACK output timing can be selected
with the DDS bit in DRAMCR. When DRAM space is accessed in DMAC single address mode at
the same time, this bit selects whether or not burst access is to be performed.
When DDS = 1: Burst access is performed by determining the address only, irrespective of the
bus master. With the DRAM interface, the DACK output goes low from the T
Figure 6.42 shows the DACK output timing for the DRAM interface when DDS = 1.
