pin. The current flowing out of and into the battery can be read via the ADC by monitoring the voltage drop over the sense resistor
between BATT and BATTISNS.
BATTISNSCC
directly to the 0.020 Ω sense resistor via a separate route from BATTISNS. The coulomb counter monitors the current flowing in/
out of the battery by integrating the voltage drop over the BATTISNCC and the BATT pin.
