1. Write value of 1 to parameter register 408002.
2. Write command code 4210 (0x1072) to command register 408001.
3. The SER clears the event log, records an “Event Log Cleared” event (code 10).

(multiple register write) or two steps using FC06 (single register write). If command is
done in two steps, it must be done in the order shown above.
