Current Register 04h (Read-Only)
Full-scale range and LSB depend on the value entered in the Calibration Register. See the TPS2480/81 Power
Measurement Engine section. Negative values are stored in two's complement format.

VALUE
The value of the Current Register is calculated by multiplying the value in the Shunt Voltage Register with the
value in the Calibration Register according to the equation:
Calibration Register
Calibration Register 05h (Read/Write)
Current and power calibration are set by bits D15 to D1 of 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
TPS2480/81 Power Measurement Engine section. This register is suitable for use in overall system calibration.
Note that the '0' POR values are all default.

D0 is a void bit and will always be '0'. It is not possible to write a '1' to D0. CALIBRATION is the value stored in D15:D1.
