2. This area is for storing the boot program provided by Renesas Technology.
The flash memory contains a user ROM area and a boot ROM area (reserved area). Figure 18.1 shows a Flash
Memory Block Diagram for R8C/1A Group. Figure 18.2 shows a Flash Memory Block Diagram for R8C/1B
Group.
The user ROM area of the R8C/1B Group contains an area (program ROM) which stores MCU operating programs
and the blocks A and B (data flash) each 1 Kbyte in size.
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.
When rewriting blocks 0 and 1 in CPU rewrite mode, set the FMR02 bit in the FMR0 register to 1 (rewrite
enabled). When the FMR15 bit in the FMR1 register to is set to 0 (rewrite enabled), block 0 is rewritable. When
the FMR16 bit to is set 0 (rewrite enabled), block 1 is rewritable.
The rewrite control 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.
the FMR1 register to 0 (rewrite enabled), block 0 is rewritable. When the FMR16 bit is set to
0 (rewrite enabled), block 1 is rewritable (only for CPU rewrite mode).
