Abstract:
A semiconductor device includes a processing system including a section of power domain circuitry and a section of coin cell power domain circuitry. The coin cell power domain circuitry is configured to, when power is initially provided to the coin cell power domain circuitry, using power provided by a power management circuit as feedback to determine that the power management circuit provides the power in response to a power request signal being a toggle signal, and determine that the power management circuit provides the power in response to the power request signal being a pulse signal.
