For each area, the bus controller can select two- or three-state access and an 8- or 16-bit data bus
width. In three-state-access areas, wait states can be inserted in a variety of modes, simplifying the
connection of both high-speed and low-speed devices.
Figure 6.18 shows an example of interconnections between the H8/3048B Group and memory.
Figure 6.17 shows a memory map for this example.
