PRODUCTION DATA
The wake up comparator is used to indicate a change in cell current while the device is in SLEEP mode. PackConfiguration() uses bits [RSNS1–RSNS0] to set the sense resistor selection. PackConfiguration() uses the [IWAKE] bit to select one of two possible voltage threshold ranges for the given sense resistor selection. An internal interrupt is generated when the threshold is breached in either charge or discharge directions. A setting of 0x00 of RSNS1..0 disables this feature.
