Memory Map
The memory map of the MB90360 Series is shown in Figure 2.3-1 .

Memory Map
The ROM data in the high-order portion of FF-bank can be seen as an image in the higher 00-bank in order
to support the small model C compiler. Since the low-order 16 bits are identical, this part of the ROM data
can be referred without using the far specification in the pointer declaration.
For example, when 00C000
H
is accessed, the contents of ROM at FFC000
H
are read. However, since the
ROM area in the FF bank exceeds 32K bytes, its entire image cannot be mirrored in the 00 bank.
The image between FF8000
H
and FFFFFF
H
is visible in bank 00, whereas the data between FF0000
H
and
FF7FFF
H
is only visible in bank FF.
