6.3.6
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 H8/3048 Group and memory.
Figure 6.17 shows a memory map for this example.
A 256-kword
16-bit bus.
Two 32-kword
devices are accessed in two states via a 16-bit bus.
One 32-kword
bus, using three-state access with an additional wait state inserted in pin auto-wait mode.
