AtRate(): 0X10/0x11
The AtRate() read-/write-word function is the first half of a two-function call-set used to set the AtRate value used
in calculations made by the AtRateTimeToEmpty() function. The AtRate() units are in mA.
The AtRate() value is a signed integer and both positive and negative values will be interpreted as a discharge
current value. The AtRateTimeToEmpty() function returns the predicted operating time at the AtRate value of
discharge. The default value for AtRate() is zero and will force AtRate() to return 65535.
AtRateTimeToEmpty(): 0x12/0x13
This read-word function returns an unsigned integer value of the predicted remaining operating time if the battery
is discharged at the AtRate() value in minutes with a range of 0 to 65534. A value of 65535 indicates
AtRate() = 0.
The gas gauge updates AtRateTimeToEmpty() within 1s after the host sets the AtRate() value. The gas gauge
automatically updates AtRateTimeToEmpty() based on the AtRate() value every 1 s.
