BQ28Z610: What is the condition to clear GaugingStatus[BAL_EN] flag?

Hello,

What could be the reason GaugingStatus[BAL_EN] flag is cleared? I tried testing the cell balancing function by using 2 cell batteries with different voltages. I noticed that after a while, GaugingStatus[BAL_EN] becomes low although QEN flag and GAUGE_EN flag are still high. If I send a GAUGE_EN() command from bqstudio, QEN flag and GAUGE_EN flag become low and BAL_EN goes high. I want to know if I can rely on bq28z610 to do cell balancing automatically or I have to periodically check the BAL_EN flag and take action accordingly. I have looked at the TRM but there is no mention on the condition of BAL_EN flag.

Thank you.
