There are six stable states (indicated by a looping arrow) and ten unstable states in the diagram. A stable state is a state the TAP can retain for consecutive TCK cycles. Any state that does not meet this criterion is an unstable state. There are two main paths through the state diagram: one to manipulate a data register and one to manipulate the instruction register. No more than one register can be manipulated at a time.
