1. When the ROM code protect is enabled by setting the ROMCP1 bits to values other than 11b, the flash memory is protected
2. Set the bits 5 to 0 to 111111b when the ROMCP1 bits are set to other than 11b.
3. To disable the ROM code protect, erase the block including the ROMCP address in standard serial I/O mode or CPU rewrite
4. The ROMCP address is set to FFh when the block including the ROMCP address is erased.
5. When the ROMCP address is set to 00h or FFh, the ROM code protect function is disabled.
