Note: 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”.
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 48k bytes, the whole area cannot be
reflected in the image for the 00 bank. The ROM data at FF4000H to FFFFFFH looks, therefore, as if it
were the image for 00400H to 00FFFFH. Thus, it is recommended that the ROM data table be stored in
the area of FF4000H to FFFFFFH
