26 / 67 page MB90860E Series 26 ■ MEMORY MAP Note : The high-order portion of bank 00 gives the image of the FF bank ROM to make the small model of the C compiler effective. Since the low-order 16 bits are the same, the table in ROM can be referenced without using the far specification in the pointer declaration. For example, an attempt to access 00C000H accesses the value at FFC000H in ROM. The ROM area in bank FF exceeds 32 Kbytes, and its entire image cannot be shown in bank 00. The image between FF8000H and FFFFFFH is visible in bank 00, while the image between FF0000H and FF7FFFH is visible only in bank FF.
