TEMP contain the reported die temperature.
VOLT contain the reported battery voltage measured on the BAT pin.
RSOC reports the nominal available capacity as a percentage of the
last measured discharge value (LMD).
NAC increments during charge(Vsrp > Vsrn) if Voltage > EDVF
threshold and decrement during discharges (Vsrp > Vsrn).
CACD reports available capacity in the battery.
CACT reports available capacity in the battery, compensated for
both discharge rate and temperature.
LMD is the measured discharge capacity of battery from full to empty.
AI reports the magnitude of the average current through the sense
resistor
TTE reports calculated time-to-empty at the measured discharge rate.
TTF reports calculated time-to-full at the measured charge rate.
SI reports measured standby current through the sense resistor.
STTE reports calculated time-to-empty at the measured standby
current value.
MLI reports the measured Maximum load current through the sense
resistor.
MLTTE reports calculated time-to-empty in minutes at the Maximum
measured discharge rate.
SAE is the calculated energy available from the battery.
AP is the calculated power delivered during a discharge.
TTECP is the time-to-empty on minutes with a constant power load.
CYCL is the cycle count since the learning cycle.
CYCT is the cycle count since a full reset.
OSOC reports the compensated available capacity as a percentage
of the last measured value(LMD).
