To read all of the data from the bq30z554 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 click 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.
The data flash configuration can be saved to a file by selecting | File | Export | and entering a file name.
In this way, a data flash file also can be retrieved, imported, and written to the bq30z554 using the Write
All button. The configuration information of the bq30z554 data is held in the data flash.
The bq30z554 allows for an automatic data flash export function, similar to the SBS Data logging
function. This feature, when selected via | Options | Auto Export |, exports data flash to a sequential
series of files named as FilenameNNNNN.gg, where N = a decimal number from 0 to 9.
The AutoExport interval is set under the | Options | menu with a minimum value of 15 seconds. The
AutoExport filename is set under the | Options | menu.
When a check is next to | AutoExport |, AutoExport is in progress. The same menu selection is used to
turn AutoExport on and off.
