23  maxim,constant-microvolt:
24    description: |
25      Battery constant voltage in uV. The charger will operate in fast
26      charge constant current mode till battery voltage reaches this level.
27      Then the charger will switch to fast charge constant voltage mode.
28      Also vsys (system voltage) will be set to this value when DC power is
29      supplied but charger is not enabled.

44      Temperature in Celsius for entering high temperature charging mode.
45      If die temperature exceeds this value the charging current will be
46      reduced by 105 mA/Celsius.

61      Threshold voltage in uV for triggering input voltage regulation loop.
62      If input voltage decreases below this value, the input current will
63      be reduced to reach the threshold voltage.
