1. When setting the FMR02 bit in the FMR0 register to “1” (enables to rewrite) and the FMR15 bit in the FMR1 register to “0” (enable to rewrite),
The flash memory contains a user ROM area and a boot ROM area (reserved area). Figure 18.1 shows
the Flash Memory Block Diagram for R8C/16 Group. Figure 18.2 shows the Flash Memory Block
Diagram for R8C/17 Group.
The user ROM area of the R8C/17 group contains an area (program ROM) which stores a
microcomputer operation program and the 1-Kbyte Block A and B (data flash).
The user ROM area is divided into several blocks. The user ROM area can be rewritten in CPU rewrite
and standard serial I/O and parallel I/O modes.
When rewriting the Block 0 and Block 1 in CPU rewrite mode, set the FMR02 bit in the FMR0 register to
“1” (rewrite enables), and when setting the FMR15 bit in the FMR1 register to “0” (rewrite enables),
Block 0 is rewritable. When setting the FMR16 bit to “0” (rewrite enables), Block 1 is rewritable.
The rewrite control program for standard serial I/O mode is stored in boot ROM area before shipment.
The boot ROM area and the user ROM area share the same address, but have an another memory.
Block 0 is rewritable. When setting the FMR16 bit to “0” (enables to rewrite), Block 1 is rewritable (only for CPU rewrite mode).
This area is to store the boot program provided by Renesas Technology.
