Description
Some products that have a battery are not fully powered down when ‘off’, but use a ‘deep-sleep’ mode to be able to start-up immediately in response to external events. To prevent emptying its battery when the product is not used for a few weeks or months, the Battery Storage Guard reads the battery level periodically, and sets the product in ‘full off’ when this level becomes too low. This register controls this feature.
Remark
This feature is only applicable on some specific products.
