The bus controller divides the 16-Mbyte address space into eight areas, 0 to 7, in 2-Mbyte units,
and performs bus control for external address space in area units. Chip select signals (CS0 to CS7)
can be output for each area. In normal mode, a part of area 0, 64-kbyte address space, is
controlled. Figure 6.6 shows an outline of the memory map.
