6.3 Overview of Bus Control
6.3.1 Area Partitioning
In advanced mode, the bus controller partitions the 16 Mbytes 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 memory map.
Chip select signals (CS0 to CS7) can be output for each area.
