Up-stream pull-up enable. SPD controls the power connection to the pull-up for the up-stream port. It
may be tied to VDD2 for operation on power up, or tied to an external control signal for application
requiring delayed enumeration.
Speed Select Down-Stream Buffer. Active high logic input. selects Full speed slew rate and timing and
logic conventions when SPU is high. This input must be set high or low and must match pin 7.
