Note : While the ROM data image of bank FF can be seen in the upper portion of bank 00, this is done only to permit
effective use of the C compiler’s small model. Because the lower 16 bits are the same, it is possible to
reference tables in ROM without declaring the “far” specification in the pointer.
For example, to access to 00C000H is to access to the ROM content of FFC000H in practice.
Because the ROM area of FF bank exceeds 48 Kbytes, all the area can be seen in bank 00.
So, the image for FF4000H to FFFFFFH can be seen in bank 00, while FE0000H to FF3FFFH can only be
seen in bank FF and FE.
