ABSTRACT:
A circuit for detecting a system reset caused by the turning on of power supply of an electronic system. The circuit comprises: latch means coupled to said power supply having a SET input and an output, said output of said latch means being reset to a first predetermined state during power-on; feedback means for receiving said output from said latch means and said system reset, said feedback means activating its output when both of said first predetermined state from said latch means' output and said system reset are present; delay means coupled to the output from said feedback means and to said latch means, said delay means activating its output a predetermined time after said delay means receiving an activated output from said feedback means, said activated output from said delay means setting said latch means to a second predetermined state such that said feedback means remains de-activated when only said system reset is present without power-on.
