In the following diagrams, CLOCK-DR is equal to TCK when the current controller state is
SHIFT-DR or CAPTURE-DR, and unchanging otherwise. The multiplexer in the center of the
diagram selects one of four inputs, depending on the status of select lines G1 and G2. The ID
Code bit is as listed in the Boundary Scan Register table located above.
