BQ78350 TCSETVCT

Other Parts Discussed in Thread: BQ78350

In the BMB BQ78350 I want the TCA flag (in BatteryStatus) to stop reacting to a valid charge termination, so that FC flag is the only one indication of a valid charge. In the register SOC Flag Config I use the value 0x12DB (TCSETVCT disabled), however this configuration isn't working. What i'm doing wrong?
