Area Division
The bus controller divides the 16-Mbyte address space into eight areas, and performs bus control
for the external address space in area units. Chip select signals (CS0 to CS7) can be output for
each area.
Figure 6.7 shows an area division of the 16-Mbyte address space. For details on address map, see
section 3, MCU Operating Modes.
