The Link asserts STP for one clock cycle
to stop the data stream currently on the
bus. If the Link is sending data to the
transceiver, STP indicates the last byte of
data was on the bus in the previous
cycle.
External 1.8V Supply input pin. This pad
needs to be bypassed with a 0.1uF
capacitor to ground, placed as close as
possible to the USB3320.
Controls the direction of the data bus.
When the transceiver has data to transfer
to the Link, it drives DIR high to take
ownership of the bus. When the
transceiver has no data to transfer it
drives DIR low and monitors the bus for
commands from the Link.
External 1.8V to 3.3V ULPI supply input
pin. This voltage sets the value of V
the ULPI signals. This pad needs to be
bypassed with a 0.1uF capacitor to
ground, placed as close as possible to
the USB3320.
