30.2
Figure 30.1
The flash memory contains a user ROM area and a boot ROM area (reserved area).
Figure 30.1 show the R8C/32A Group Flash Memory Block Diagrams.
The user ROM area contains program ROM and data flash.
Program ROM: Flash memory mainly used for storing programs
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.
