When DDS = 0 or EDDS = 0: When continuous synchronous DRAM space is accessed in
DMAC or EXDMAC single address transfer mode, full access (normal access) is always
performed. With the synchronous DRAM interface, the '$&. or ('$&. output goes low from
the T
state.
r
In modes other than DMAC or EXDMAC single address transfer mode, burst access can be used
when accessing continuous synchronous DRAM space.
Figure 6.61 shows the '$&. or ('$&. output timing for the synchronous DRAM interface
when DDS = 0 or EDDS = 0.
