Notes: Do not access the reserved area. If the reserved area is accessed, the correct operation
cannot be guaranteed. In single-chip mode, only the on-chip ROM, on-chip RAM, and on-
chip peripheral modules can be accessed; the other areas cannot be accessed.
* The bus width is selected by the register setting.
