Markus,
The X10 bit is bit 7 of the low byte in the pack Configuration Register (p20 of the Dec 2012 revised data sheet). The description is once again confusing as the first sentence suggests "settings and reports will take on a value of ten times normal." Then the next sentence indicates, "This setting has no actual effect within the gauge." The host uses this bit to indicate that "a scaling factor" has been applied during the calibration of the gas gauge whether the scaling is ten times, four times, two times, etc.
Thanks,
