Abstract: The present invention discloses a detection control circuit for preventing a leakage current, which comprises a register unit comprising a clock signal input terminal for receiving a clock signal; a reset signal input terminal, for receiving a reset signal; a signal generating terminal, for generating a logic signal; and a logic gate, coupled to said register unit, comprising a first signal input terminal for receiving said logic signal; a second signal input terminal for receiving a control signal; and a signal output terminal, for outputting an output signal according to said logic signal and said control signal; wherein said control signal controls said logic gate so as to keep said output signal to be in a fixed state which detects a leakage current in an integrated circuit due to the process flaw.

Abstract: The present invention relates to a control method for the operation modes of an oscillator and the apparatus thereof, for which the method and the apparatus can be applied to the electronic circuits with multi-operation modes of the oscillator so as to correctly choose the desirable oscillator operation mode. Furthermore, an oscillator checking circuit sets up the oscillation mode automatically and judges if the oscillator operates properly. Hence, there is no need for the user to set up the oscillator operation mode manually.
