    There are two different kinds of NVMs – Fixed NVM (FNVM) and NVM.

    For FNVM, data will not get lost with software (new control strategy) updates. But it needs to be configured in EcoCoder.
    For NVM, data will be erased with software updates.

    For NVM, and FNVM, the low-level logic is that the micro needs to access the entire address to get a single data, while EEPROM only needs to access the address of specific data to get the value of it.
