8.6.2 ChargeCurrent Register (I²C address = 03/02h) [reset = 0000h]

To set the charge current, write 16-bit ChargeCurrent() command (REG0x03/02h()) using the data format listed Figure 8-17.

With 5-mΩ sense resistor, the charger provides charge current range of 0 A to 16.256 A, with a 128-mA step resolution. With 10-mΩ sense resistor, the charger provides charge current range of 0 A to 8.128 A, with a 64-mA step resolution.

Upon POR, ChargeCurrent() is 0 A. Below scenarios will also reset Charge current to zero:

CELL_BATPRESZ going LOW (battery removal).
STAT_AC is not valid(Adapter removal).
RESET_REG is asserted and reset all registers.
Charge voltage is written to be 0 V.
Watch dog event is triggered.

Charge current is not reset in force converter latch off fault (REG0x20[2]), and ACOC/TSHUT/SYSOVP/ACOV/VSYS_UVP/BATOVP/BATOC faults.
