Notes: 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 00C000
H
is to access to the ROM content of FFC000
H
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 FF4000
H
to FFFFFF
H
can be seen in bank 00, while FE0000
H
to FF3FFF
H
can only be
seen in bank FF and FE.
