The settings can be configured using the Data Flash screen.
Figure 9. Data Flash Screen, 1st Level Safety Class
To read all the data from the bq20z70 data flash, click on menu option | Data Flash | Read All |.
To write to a data flash location, click on the desired location, enter the data, and press <Enter>, which
writes the entire tab of flash data, or select menu option |Data Flash|Write All|. The data flash must be
read before any writes are performed to avoid any incorrect data being written to the device.
The | File | Special Export | menu options allows the data flash to be exported, but it configures the
exported data flash to a learned state ready for mass production use.
The data flash configuration can be saved to a file by selecting | File | Export |, and entering a file name. A
data flash file can also be retrieved in this way, imported, and written to the bq20z70 using the | Write All |
button.
The configuration information of the bq29330 and module calibration data is also held in the bq20z70 data
flash.
