Abstract: The present disclosure relates to a method for managing the deep sleep mode of an embedded system. In embodiments, the method includes determining a value of the electrical charge used, during a deep sleep mode of the system, for saving software-context data into a non-volatile memory of the system; determining a value of a current used, during a deep sleep mode of the system, for saving software-context data into a volatile memory of the system; determining, from the previously determined values, a threshold value defining a duration beyond which a power consumption caused by saving software-context data into the non-volatile memory is less than that into the volatile memory; saving the software-context data into the non-volatile or volatile memory according to the expected duration of deep sleep mode of the system.

Abstract: The presence and/or state of an accessory having a connector of a first type (e.g. male connector) adapted to be plug into a connector of a second type (e.g. female connector) of an electronic device is detected based on an analysis of an electrical line coupled to the female connector of the device, wherein the electrical line analysis is started only when it is determined that the connector of the accessory is completely inserted into the connector of the device.
