*Most probable condition
Note 1: If a depleted battery is inserted while the charger is in this state, the
charger must be reset to initiate charging.
Note 2: See section on “Adapter Limiting”.
Note 3: Blank fields indicate no change, not considered, or other states impact
value.
Note 4: Battery voltage thresholds do not include comparator hysterisis.
Thresholds specify the VLH value.
