Memory Map in Each Operating Mode

Figures 3.1 to 3.4 show memory maps of the H8/3062 Series. In the expanded modes, the address
space is divided into eight areas.
The initial bus mode differs between modes 1 and 2, and also between modes 3 and 4.
The address locations of the on-chip RAM and on-chip registers differ between the 64-kbyte mode
(mode 6), the 1-Mbyte modes (modes 1, 2, and 7), and the 16-Mbyte modes (modes 3, 4, and 5).
The address range specifiable by the CPU in the 8- and 16-bit absolute addressing modes (@aa:8
and @aa:16) also differs.

Comparison of H8/3062 Series Memory Maps

In the H8/3062 Series, the address maps vary according to the size of the on-chip ROM and RAM.
The internal I/O register space is the same in all models, and the H8/3062F-ZTAT A-mask version
and H8/3062 have the same address map. Table 3.4 shows the various address maps in mode 5.
