Still unclear which parameters have to be scaled with ipscale=1

Part Number: BQ78350-R2-DEVICE-FW

Hi,

after spending many hours of reading all documentations, incl. datasheet, app-notes, presentation on the "high discharge rate scaling" i am still unsure which parameters have to be scaled.

I want to use IPSCALE=1 to support current measurements up to 320A (instead of 32.768A.

Question: Do all parameter related to "current in mA" need to be reescaled by factor 0.1 (divied by 10)? I found more than 54 parameters?

Please help...?

        I think IPScales is only for information purpose for host device, once this is set, then host knows that all current related data read from the gauge should be multiplied by 10.

        Please correct me if above is not correct.
