Abstract
The present invention relates to a reset signal generator adapted to be used with a microprocessor for generating a reset signal to initialize the microprocessor, which includes an oscillator to generate a fixed clock signal, a counter electrically connected to the oscillator for generating a cyclic signal in response to the fixed clock signal and outputting the reset signal at an end of a period of the cyclic signal, and a clear signal generating device electrically connected to the counter and outputting a clear signal for the counter in response to an output signal from the microprocessor. The present invention ensures that when the microprocessor is abnormal or down it will be initialized by the reset signal.
