1. A method for initializing an electronic device, the method comprising the steps of: detecting a change in a power supply voltage; generating a signal to switch a power-on-reset (POR) circuit from a first power state to a second power state responsive to detecting a change in the power supply voltage; determining if the power supply voltage has fallen below a minimum operating voltage; and responsive to the determination that the power supply voltage has fallen below the minimum operating voltage, generating an initialization signal for the electronic device.
