    Hello Stas,

    Looking at the bqStudio image you provided, XDSG/XCHG are enabled in the 0x66 Alarm Enable() register. This enables which alarm sources are enabled.

    This explained in Section 12.2.19 Alarm Enable Register and 6.6 ALERT Pin Operation of the TRM.

    Best Regards,

    Luis Hernandez Salomon
