■ MEMORY MAP
Note : To select models without the ROM mirror function, refer to the “ROM Mirror Function Selection Module” in
Hardware Manual. The image of the ROM data in the FF bank appears at the top of the 00 bank, in order
to enable efficient use of small C compiler models. The lower 16-bits of the FF bank addresses are allocated
to the same addresses as the lower 16-bits of the 00 bank, making it possible to reference tables in ROM
without declaring the “far” modifier with the pointers. For example, when an access is made to the address
00C000H, the actual address to be accessed is FFC000H in ROM. Because the size of the FF bank ROM
area exceeds 32 Kbytes, it is not possible to view the entire region in the 00 bank image. Therefore because
the ROM data from FF8000H to FFFFFFH appears in the image from 008000H to 00FFFFH, it is
recommended that ROM data tables be stored in the area from FF8000H to FFFFFFH.
* : Evaluation products do not contain internal ROM. Treat this address as the ROM decode area used by the tools.
