6.3.3
The H8/3006 and H8/3007 memory interfaces comprise a basic bus interface that allows direct
connection of ROM, SRAM, and so on; a DRAM interface that allows direct connection of
DRAM; and a burst ROM interface that allows direct connection of burst ROM. The interface can
be selected independently for each area.
An area for which the basic bus interface is designated functions as normal space, an area for
which the DRAM interface is designated functions as DRAM space, and area 0 for which the burst
ROM interface is designated functions as burst ROM space.
6.3.4
For each of areas 0 to 7, the H8/3006 and H8/3007 can output a chip select signal (CS
goes low when the corresponding area is selected. Figure 6.4 shows the output timing of a CSn
signal.
