■ MEMORY MAP
Note: The ROM data of bank FF is reflected to the upper address of bank 00, realizing effective use of the C
compiler small model. The lower 16-bit is assigned to the same address, enabling reference of the table on
the ROM without stating “far”. For example, if an attempt has been made to access 00C000H, the contents
of the ROM at FFC000H are accessed actually. Since the ROM area of the FF bank exceeds 32 K bytes, the
whole area cannot be reflected in the image for the 00 bank. The ROM data at FF8000H to FFFFFFH looks,
therefore, as if it were the image for 008000H to 00FFFFH. Thus, it is recommended that the ROM data table
be stored in the area of FF8000H to FFFFFFH.
