Figure 26.1
The flash memory contains a user ROM area and a boot ROM area (reserved area).
Figure 26.1 shows the R8C/36T-A Group Flash Memory Block Diagram.
The user ROM area contains program ROM and data flash.
Program ROM: Flash memory mainly used for storing programs
Data flash: Flash memory mainly used for storing data to be rewritten
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.
