Memory Interfaces

The H8/3028 Group 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.
