3.6
Figures 3.1 to 3.2 show memory maps of the H8/3024 Group. 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.
3.6.1
In the H8/3024 Group, 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. Table 3.4 shows the various address maps
in mode 5.
Table 3.4
3.6.2
The H8/3024 Group memory map includes reserved areas to which access (reading or writing) is
prohibited. Normal operation cannot be guaranteed if the following reserved areas are accessed.
Reserved Area in Internal I/O Register Space: The H8/3024 Group internal I/O register space
includes a reserved area to which access is prohibited. For details see Appendix B, Internal I/O
Registers.
