1. In CPU rewrite mode, set the MCD register to be the 10-MHz CPU clock frequency or less and set the PM12
3. Exit CPU rewrite mode after executing the read array command.
4. When the FMR05 bit is set to "1", the user ROM area can be accessed.
5. To change the FMR01 bit setting from "1" to "0", enter read array mode to write to addresses 0057
2. To set the FMR01 bit to "1", set it to "1" in 8-bit unit immediately after setting it first to "0". Do not generate an
