IBAT[11:0]
Absolute Current , 0.000A to 4.095A range(0.00A to 4.063A clamp), 1mA steps (RSENS=10mohm).
Absolute Current , 0.000A to 1.365A range(0.00A to 4.063A clamp), 0.33mA steps (RSENS=30mohm).
Series of IBAT_DIR and IBAT[11:0] (address from 5Bh to 5Ch) should be read in accordance with continuous manner,
so stop condition should not be inserted during reading these registers.

VBAT[12:0]
Measured Battery Voltage. 0.000V to 8.191V range(0.4V to 5.6V clamp), 1mV steps.
This register value is also used for Over-Voltage detection and some Charger functions.
Series of VBAT[12:0] (address from 5Dh to 5Eh) should be read in accordance with continuous manner,
so stop condition should not be inserted during reading these registers.
