Control Transfers at
Control End-point EP0
The description given below is for the function control end-point, but applies to the hub control
end-point as well if the proper registers are used.
The following illustration describes the three possible types of control transfers – Control
Write, Control Read and No-data control:
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.
