The following state diagram shows how the various state transitions are triggered. Additional
decision making may take place within the response states to determine the next expected
state. Unmarked arcs represent transitions that trigger immediately following completion of the
response state processing. Stable states, those requiring an interrupt to exit having no
unmarked arcs as exit paths, are shown in bold.
