MEMORY MAP
MB90F481/F482/487B/488B/483C/F488B/V480/V485B/F489B
*1 : No memory cells from FC0000
H
to FC7FFF
H
and FE0000
H
to FE7FFF
H
.
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 are the same, enabling reference to tables in ROM without using the for specification in the 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 Kbytes 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.
