BQ27220: Golden image for current calibration data

Part Number: BQ27220
Other Parts Discussed in Thread: BQSTUDIO

Tool/software:

Do CC gain, CC delta get programmed during OTP programming along with other data or do I have to write it with the driver manually everytime the device boot up?

I've performed calibration steps as well as OTP programming on one of my chip for testing. I've noticed that doing "read all" in BQstudio to get the RAM value of units that has been calibrated by golden image, CC Offset - CC Delta did not quite get updated along with the data I previously had while doing calibration. For example, the expected CC Gain that I had was 0.2150 but it received a defaulted value of 0.2380 instead.

Board Offset -- CC deadband did get updated however as the present OTP parameter included them but I can't find any parameter in present OTP for CC Offset - CC Delta
