Single address transfer by the DMAC or EXDMAC takes place as a full access (normal access).
The DACK and EDACK signals are asserted within the Tr cycle and the BS signal is also asserted
during the Tr cycle.
When the DRAM space is accessed with other than the single address transfer by the DMAC or
EXDMAC, a fast-page access is available.
Figure 9.59 shows an output timing example of the DACK and EDACK signals when DDS = 0 or
EDDS = 0.
