: In models where address 2# coincides with 004000
H
, there is no external area.
The image of FF bank ROM is reflected in the top of the 00 bank, for greater efficiency in using the C compiler
for small models. The lower 16-bit address on the FF bank is the same as the lower 16-bit address on the 00
bank, so that it is possible to reference tables in ROM without using the pointer for a far specification.
For example, when accessing 00C000
H
, it is actually the content of ROM at FFC000
H
that is accessed. Here,
because the ROM area on the FF bank exceeds 48 KB, it is not possible to view the entire area in the image on
the 00 bank. Therefore, the image from FF4000
H
to FFFFFF
H
is visible on the 00 bank, and FF0000
H
to FF3FFF
H
is visible only on the FF bank.
