3. MCU Operating Modes
3.6 Memory Map in Each Operating Mode
Figures 3.1 and 3.2 show a memory maps of the H8/3006 and H8/3007. 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 internal I/O registers differ between the 1-Mbyte
modes (modes 1, 2), and the 16-Mbyte modes (modes 3, 4). 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 Note on Reserved Areas
The memory map of the H8/3006 and H8/3007 includes reserved areas to which read/write access
is prohibited. Note that normal operation is not guaranteed if the following reserved areas are
