MEMORY MAP
Note : To select models without the ROM mirror function, see the “ROM Mirror Function Selection Module.” 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-bit address for the FF bank will be assigned to the same address,
so that tables in ROM can be referenced without declaring a “far” indication with the pointer. For example
when accessing the address 00C000
H
, the actual access is to address FFC000
H
in ROM. Here the FF bank
ROM area exceeds 48 KB, so that it is not possible to see the entire area in the 00 bank image. Therefore
because the ROM data from FF4000
H
to FFFFFF
H
will appear in the image from 004000
H
to 00FFFF
H
, it is
recommended that the ROM data table be stored in the area from FF4000
H
to FFFFFF
H
.
