The ROM code protect function disables to read and change the internal flash memory by the OFS register in
parallel I/O mode.
Figure 19.4 shows the OFS Register.
The ROM code protect function is enabled by writing 0 to the ROMCP1 bit and 1 to the ROMCR bit and
disables to read and change the internal flash memory.
Once the ROM code protect is enabled, the content in the internal flash memory cannot be rewritten in parallel
I/O mode. When the ROM code protect is disabled, erase the block including the OFS register with CPU
rewrite mode or standard serial I/O mode.

The OFS register is on the flash memory. Write to the OFS register w ith a program. After w riting is completed, do not
w rite additions to the OFS register.
To use the pow er-on reset, set the LVD1ON bit to 0 (voltage monitor 1 reset enabled after reset).
If the block including the OFS register is erased, FFh is set to the OFS register.
