NOTES:
The flash memory contains a user ROM area and a boot ROM area (reserved area).
Figure 19.1 shows the Flash Memory Block Diagram for R8C/26 Group. Figure 19.2 shows a Flash Memory Block
Diagram for R8C/27 Group.
The user ROM area of the R8C/27 Group contains an area (program ROM) which stores MCU operating programs
and 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 is set to 0 (rewrite enabled), block 0 is rewritable. When the
FMR16 bit is set to 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.
1. When the FMR02 bit in the FMR0 register is set to 1 (rewrite enabled) and the FMR15 bit in the FMR1 register is set to 0
2. This area is for storing the boot program provided by Renesas Technology.
(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).
