Memory Map
The flash memory contains a user ROM area and a boot ROM area (reserved area).
Figure 20.1 shows the Flash Memory Block Diagram for R8C/2G Group.
The user ROM area contains program ROM.
The user ROM area is divided into several blocks. The user ROM area can be rewritten in CPU rewrite mode and
standard serial I/O and parallel I/O modes.
The rewrite control program (standard boot program) for standard serial I/O mode is stored in the boot ROM area
before shipment. The boot ROM area and the user ROM area share the same address, but have separate memory
areas.
