Abstract: In an embodiment a method for managing a low-power mode of an electronic device includes at a first request for transitioning an electronic device to a low-power mode, storing values of a first counter and a second counter of the electronic device on a first edge of a first clock and at a second request for transitioning the electronic device out of the low-power mode calculating a number of periods of a second clock between a second edge of the first clock and the first edge, the second edge being later than the first edge and updating the value of the second counter with a calculated value, wherein the first clock drives the first counter and the second clock drives the second counter, the second clock being faster than the first clock.
