When DDS = 0 or EDDS = 0: When DRAM space is accessed in DMAC or EXDMAC single
address transfer mode, full access (normal access) is always performed. With the DRAM interface,
the DACK or EDACK output goes low from the T
In modes other than DMAC or EXDMAC single address transfer mode, burst access can be used
when accessing DRAM space.
Figure 6.42 shows the DACK or EDACK output timing for the DRAM interface when DDS = 0 or
EDDS = 0.
