MB90670/675 Series

s MEMORY MAP
Notes:
The ROM data of bank FF is reflected in the upper address of bank 00, realizing effective use of the C compiler
small model. The lower 16-bit of bank FF and the lower 16-bit of bank 00 is assigned to the same address,
enabling reference of the table on the ROM without stating “far”.
However, the ROM area of the MB90678/P678 exceeds 48 Kbytes, and for this reason, the image from FF4000H
to FFFFFFH is reflected on bank 00 and image from FF0000H to FF3FFFH bank FF only.
In the MB90670/675 series, the upper 4-bit of the address are not output to the external bus. For this reason,
the maximum area accessible is 1 Mbyte. The same address is accessed through different banks in different
images.
For example, accessing “A00000H” and “B00000H” accesses the same address on the external bus.
To prevent the memory or I/O from being accessed through images, and the data from being destroyed, it is
recommended to limit number of banks to a maximum of 16 so that the banks are mapped without interfering
each other. Caution must be also taken when masking the upper address with the external address output
control register (HACR).
