BQ27421EVM Documentation and BQ27421 Ref Manual Data Memory Discussions Don't Match

Other Parts Discussed in Thread: BQSTUDIO

The bq27421 Data Memory descriptions in these two documents are inconsistent.  As an example, the EVM document includes parameters Min Taper Capacity and Current Taper Window for the Charge Termination subclass.  The reference manual makes no mention of these parametes within the subclass.  This makes it very confusing for Data Memory programming understanding.  Is there documentation for this part that is more current and more consistent?

    hi Brian,
    Those two parameters which you mentioned are actually part of the data memory but are private (hidden) parameters which you do not have access to so do not worry about configuring or setting them. Pls refer to the technical reference manaul as well as the parameters listed in bqstudio for a list of available parameters to you. Also when programming the device, your gm.fs (flashtream) file will contain all parameters, both hidden and unhidden so you needn't worry about those.

    thanks
