EEPROM Write Mode

If the holding register write command (06h), etc. is used to write "1" into the holding register for
EEPROM write mode (0902h), the EEPROM, the EEPROM write mode will become active.
If data is changed using the holding register write command (06h) after switching to the EEPROM
write mode, the new data is written into both the volatile memory for operation (RAM) and
nonvolatile memory for storage (EEPROM). At the same time, the EEPROM write mode is
cancelled.
If any command other than the holding register write command (06h) is received after switching
to the EEPROM write mode, the EEPROM write mode is cancelled.
