3Description:
4	Read/Write limit on current which may
5	be drawn from the ac (Accessory Charger) or

26		"off"  - do not draw any power.
27		"continuous"
28		       - activate mode described as "linear" in
29		         TWL data sheets.  This uses whatever
30			 current is available and doesn't switch off
31			 when voltage drops.
32
33			 This is useful for unstable power sources
34			 such as bicycle dynamo, but care should
35			 be taken that battery is not over-charged.
