Section 6 Bus Controller
6.3
6.3.1
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. In normal mode, it
controls a 64-kbyte address space comprising part of area 0. Figure 6.2 shows an outline of the
memory map.
Chip select signals (CS0 to CS7) can be output for each area.
