Each time DIR changes, a “turn-around” cycle occurs where neither the Link nor PHY drive the data
bus for one clock cycle. During the “turn–around“cycle, the state of DATA[7:0] is unknown and the PHY
will not read the data bus.
Because USB uses a bit-stuffing encoding, some means of allowing the PHY to throttle the USB
transmit data is needed. The ULPI signal NXT is used to request the next byte to be placed on the
databus by the Link layer.
