CC Gain and CC Delta are two parameters used to calibrate current measurement readings.
CC Gain is the gain factor for calibrating Sense Resistor, Trace, and internal coulomb counter (integrating ADC delta sigma) errors. It is used in the algorithm that reports charge and discharge in and out of the battery through the RemainingCapacity() register. The difference between CC Gain and CC Delta is that the algorithm that reports AverageCurrent() cancels out the time base because AverageCurrent() does not have a time component (it reports in mA) and CC Delta requires a time base for reporting RemainingCapacity() (it reports in mAh). The default values are based off readings on TI provided EVMs and will need to be changed based on customers' boards.
