Note : Every voltage value is measured when the voltage at GND pin is 0V. The maximum and the minimum of each
voltage value are shown in absolute values.
Regarding current directions, inflow current is shown in a positive value and outflow current is shown in a
negative value. The maximum and the minimum of each current value are shown in absolute values.
