Figure 3.1 shows a memory map for each of the operating modes.
The address space is 64 kbytes in modes 1 to 3 (normal modes), and 16 Mbytes in modes 4 to 7
(advanced modes).
The H8S/2351’s on-chip ROM contains 64 kbytes, but only 56 kbytes are available in modes 2
and 3 (normal modes).
The address space is divided into eight areas for modes 4 to 7. For details, see section 6, Bus
Controller.
