*1 : Writing into the system ROM is not allowed.
*2 : Do not use the user program to write into the standard ROM. As the write count of the standard ROM is limited, doing
so will reduce the operation life of the C Controller module.
*3 : Since this is a volatile memory, files are lost upon power OFF. Use it when creating temporary files. To store files in the
work RAM, create a RAM disc.
*4 : To store files in the battery backup RAM, create a standard RAM.
