4.2.6.14 EEPROM Initialize

You can initialize the MCU PWB EEPROM (NVM).
Do not initialize the EEPROM unless instructed to do
so in this manual.
If you initialize the EEPROM, do the following:
 Read the NVM numbers using the EEPROM Read.
 Execute the NVM Write in the [Service] tab.
 Write the data (that has been read) using the
EEPROM Write. (Also execute the NVM Write in the
[Service] tab.)
You need to send the DIAGOFF command to actually initialize the
EEPROM.
