Area Partitioning

In advanced mode, the bus controller partitions the 16-Mbyte address space into eight areas, 0 to
7, in 2-Mbyte units, and performs bus control for external space in area units. Figure 6-2 shows an
outline of the area partitioning.
Chip select signals (CS0 to CS7) can be output for each area.
