(source capability) the sink side requests an appropriate voltage from the power profile to the source side. (request) in response to the sink side voltage request, if th e source side is able to deal with it, notifies the sink side that it acknowledged. (accept) the source side outputs the requested voltage to th e vbus pin. after outputting the required voltage, the source s ide notifies the sink side that the requested voltage has been output. (ps_rdy) after confirming the requested voltage, the sink si de turns on the fet switch on the vbus line. ?
