.
The upper part of the 00 bank is set up to mirror the image of FF bank ROM, to enable efficient use of small
model C compilers. Because the lower 16-bit address of the FF bank and the lower 16-bit address of the 00
bank is the same, enabling reference to tables in ROM without the “far” pointer declaration.
For example, in accessing address 00C000
H
it is actually the contents of ROM at FFC000
H
that are accessed.
If the MS bit in the ROMM register is set to “0”, the ROM area in the FF bank will exceed 48 K bytes and it is
not possible to reflect the entire area in the image in the 00 bank. Therefore the image from FF4000
H
to FFFFFF
H
is reflected in the 00 bank and the area from FF0000
H
to FF3FFF
H
can be seen in the FF bank only.
