17.2.62 ManufacturerAccess() 0xF082 OutputCellVoltageCCandTempforCalibration
This command instructs the device to output the raw values for calibration purposes on
ManufacturerBlockAccess() or ManufacturerData(). All values are updated every 250 ms and the format of
each value is 2's complement, MSB first. This mode includes an internal short on the coulomb counter
inputs for measuring offset.
