The transceiver asserts NXT to throttle
the data. When the Link is sending data
to the transceiver, NXT indicates when
the current byte has been accepted by
the transceiver. The Link places the next
byte on the data bus in the following
clock cycle.
ULPI bi-directional data bus.

ULPI bi-directional data bus.
This signal, along with REFSEL[1] and
REFSEL[2] selects one of the available
reference frequencies as defined in
Table
Note: This signal must be tied to VDDIO
when in ULPI 60MHz REFCLK IN mode.
