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. 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 CS3) can be output for areas 0 to 3.
Note: * ZTAT, mask ROM, and ROMless versions only.

Description
Addresses H'010000 to H'01FFFF are in on-chip ROM (in the H8S/2345)
Addresses H'010000 to H'017FFF are in on-chip ROM and addresses H'018000 to
H'01FFFF are a reserved area (in the H8S/2344)
Addresses H'010000 to H'01FFFF are a reserved area (in the H8S/2343 and
H8S/2341)
Addresses H'010000 to H'01FFFF are external addresses (external expansion mode)
or a reserved area * (single-chip mode)
