*1: In MB90F489B model, an access to F8 bank and FC bank is not performed in the single-
chip mode and internal ROM/external bus mode as shown in Figure A-2.
*2: Because built-in RAM area in MB90F489B model is larger than that in MB90V485B
model, the emulation area that exceeds 004000
at tool side.

compiler's small model to be more efficiently utilized. Because the lower 16 bits are identical, pointer
declarations do not require the "far" specification to refer the table in ROM. For example, an access
to 00C000
because the ROM area in bank FF exceeds 48 KB if the MS bit of the ROMM register is set to "0",
not all of the areas can be viewed via their image in bank 00. For this reason, an image of the area
