rite Mode
• To set the EEPROM write mode, use the Write to Holding Register (06 hex) command etc. to write 1
to the holding register for the EEPROM write mode (0902 hex).
• In the EEPROM write mode, the data changed by the Write to Holding Register (06 hex) command is
written to both the RAM (volatile memory for operation) and the EEPROM (non-volatile memory for
storage). Then, the EEPROM write mode is canceled.
• The EEPROM write mode is canceled also if a command other than the Write to Holding Register (06
hex) command is received in the EEPROM write mode.
