Memory Map in Each Operating Mode
Figures 3.1 to 3.5 show memory maps for each of the operating modes.
The address space is 64 kbytes in modes 1 and 3 (normal modes), and 16 Mbytes in mode 2
(advanced mode).
The on-chip ROM capacity is 64 kbytes (H8S/2142, H8S/2147, and H8S/2147N), 96 kbytes
(H8S/2143), or 128 kbytes (H8S/2144 and H8S/2148), but only 56 kbytes are available in mode 3
(normal mode).
Do not access the reserved area and addresses of modules not supported by the product. Note that
normal operation is not guaranteed when these regions are accessed.
