BQ34Z110 CHG Flag

Hi

I am using bq Gas Gauge Eval s/w bq34z110 v0.04

Is it normal that, during a "Step 8 Optimization Cycle" on a 12V 7Ah Yuasa PbA battery,  a few minutes after the Flags.DSG bit is set, the Flags.CHG bit is also set.

Charging was done using bench psu set to 13.8V. Discharge using resistor.

Relevant settings FYI:

Dsg Current Threshold = 10mA

Chg Current Threshold = 75mA

Quit Current = 40mA

Dsg Relax Time = 60s

Chg Relax Time = 10s

Quit Relax Time = 1s

I am also having considerable difficulty changing any of the Data Flash settings. Are changes to Data Flash settings prohibited when IT is enabled? 

Thanks

Simon
