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.
For setting of the ROM mirror function, see “s PERIPHERAL RESOURCE 17. ROM Mirror Function
Selection Module”.
Reference:
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 K bytes, 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 mirror image can be shown 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.
