Shunt Calibration Register 15h (Read/Write)
Current and power calibration are set in the Calibration Register. Note that bit D0 is not used in the calculation.
This register sets the current that corresponds to a full-scale drop across the shunt. Full-scale range and the LSB
of the current and power measurement depend on the value entered in this register. See the Programming the
TMP512/13 Power Measurement Engine section. This register is suitable for use in overall system calibration.
Note that the '0' POR values are all default.
