BQ76952: DDSG and DCHG turned low during the board offset calibration

Part Number: BQ76952

Tool/software:

Customer implemented the board offset calibration with 0 current and discharging current, but DDSG and DCHG turned off for a short time (300ms), as showed in the below waveform.

CH2: DDSG,  CH3:DCHG  (with 50A discharging current calibration)

  

With 0A current calibration

And they tried to debug online, and found the connection was interrupted when implementing the command "CONFIG_UPDATE,Subcommand 0X090".

Could you please help with this urgent issue?
