Aspects of a method and system for blocking data in scan registers from being shifted out of a device may comprise preventing data intrusion in an integrated circuit by generating a device reset signal prior to entering scan mode. The method may further comprise detecting an attempt to enter said scan mode. The device reset signal may also be an internal reset signal. A subsequent device reset signal may be generated after entering scan mode. The subsequent device reset signal may be an internal pulse signal. The method may further comprise clearing stored data in an integrated circuit after generating a subsequent device reset signal.
