1. An integrated circuit comprising:

  • a core-logic providing a core-logic output;

    an isolation circuit in communication with said core-logic, operable to selectively provide an output corresponding to one of said core-logic output and a predetermined value;

    a latch interconnected to said isolation circuit, receiving said output of said isolation circuit;

    a power consumption controller in communication with said core-logic, said latch and said isolation circuit, said controller operable to;

    control said latch to store a value of said core-logic output and provide a corresponding output;

    control said isolation circuit to provide an output corresponding to said predetermined value, at said output of said isolation circuit; and

    transition said core-logic from a high power state to a low power state.
