17 / 92 page  MB90800 Series DS07-13733-6E 17 ■ MEMORY MAP Memory Map of MB90800 Series Notes : • When the ROM mirror function register has been set, the mirror image data at higher addresses ( “FF4000H to FFFFFFH” ) of bank FF is visible from the higher addresses ( “008000H to 00FFFFH”) of bank 00. • The ROM mirror function is for using the C compiler small model. • The lower 16-bit addresses of bank FF are equivalent to those of bank 00. Note that because the ROM area of bank FF exceeds. 32 Kbytes, all data in the ROM area cannot be shown in mirror image in bank 00. • When the C compiler small model is used, the data table can be shown as mirror image at “008000H to 00FFFFH ”by storing the data table at “FF8000H to FFFFFFH”. Therefore, data tables in the ROM area can be referenced without declaring the far addressing with the pointer. FFFFFFH 00FFFFH 008000H 007917H 007900H 000100H 0000CFH 0000C0H 0000BFH 000000H * : ROM is not built into MB90V800. F80000H is ROM decipherment region on the tool side.
