6.6.2
When DRAM space is accessed in DMAC single address mode, full access (normal access) is always performed. The
DACK output goes low from the T
In modes other than DMAC single address mode, burst access can be used when accessing DRAM space.
Figure 6-29 shows the DACK output timing for the DRAM interface when DDS = 0.

6.7.1
With the H8S/2357 Group, external space area 0 can be designated as burst ROM space, and burst ROM interfacing can
be performed. The burst ROM space interface enables 16-bit configuration ROM with burst access capability to be
accessed at high speed.
Area 0 can be designated as burst ROM space by means of the BRSTRM bit in BCRH. Consecutive burst accesses of a
maximum of 4 words or 8 words can be performed for CPU instruction fetches only. One or two states can be selected for
burst access.
