    Please use the definition from the TRM and datasheet.

    Some reserved bits will impact the algorithm. They are not officially documented (though bqStudio shows their name) and must be set to the default values. In your example, LFOONLY and FCC16X were meant to be reserved and set to 1 (LFOONLY = reserved) and 0 (FCC16 = reserved).
