MICRO CONTROLLER AND METHOD FOR CONTROLLING THE SAME

摘要

PURPOSE: A micro controller and a method for controlling the same is provided to easily design a circuit by dealing with change of outside power supply in itself without an outside circuit required for solving a problem of power supply change provided from the outside. CONSTITUTION: A micro controller is applied to a power supply from an outside, in which a power down controlling circuit(200) is installed in an inside thereof. A system reset signal is output by a pulse signal from the outside and a system reset terminating signal is output after reset operation by the reset signal. A state of the power supply is detected and a system reset signal is output based on the state of the power supply system. A system reset terminating signal is output after reset operation by the reset signal.
