The flash memory contains the user ROM area and the boot ROM area (reserved area). Figures 18.1 to
18.4 show a block diagram of the flash memory. The user ROM area has space to store the microcomputer
operation program in single-chip mode and two 2-Kbyte spaces: the block A and B.
The user ROM area is divided into several blocks. The user ROM area can be rewritten in CPU rewrite,
standard serial input/output, and parallel input/output modes.
However, to rewrite program in block 0 and 1 in CPU rewrite mode, set the FMR02 bit in the FMR0 register
to “1” (block 0, 1 rewrite enabled) and the FMR16 bit in the FMR1 register to “1”(blocks 0 to 4 rewrite
enabled).
Also, to rewrite program in blocks 2 to 4 in CPU rewrite mode, set the FMR16 bit in the FMR1 register to “1”
(blocks 0 to 4 rewrite enabled). When the PM10 bit in the PM1 register is set to “1”(data space access
enabled), block A and B can be available for use.
The boot ROM area (4-byte) is a reserved area. This boot ROM area has a standard serial I/O mode control
program stored before shipping. Do not rewrite the boot ROM area.

NOTES:
1. To specify a block, use the maximum even address in the block.
2. Blocks A and B are enabled for use when the PM10 bit in the PM1
3. Blocks 0 and 1 are enabled for programs and erasure when the
4. The Boot ROM area is reserved. Do not rewrite.
5. Blocks 2 and 3 are enabled for programs and erasure when the
register is set to "1".
FMR02 bit in the FMR0 register is set to "1" and the FMR16 bit in
the FMR1 register is set to "1". (CPU rewrite mode only)
FMR16 bit in the FMR1 register is set to "1". (CPU rewrite mode
only)
