Figure 32.1 shows the R8C/34M Group Flash Memory Block Diagram.
The user ROM area contains program ROM and data flash.

Data flash:
The user ROM area is divided into several blocks. The user ROM area can be rewritten in CPU rewrite mode,
standard serial I/O mode, or parallel I/O mode.
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 is allocated separately from the user ROM area.
