Description
ULPI Clock Out Mode:
60MHz ULPI clock output. All ULPI signals are driven
synchronous to the rising edge of this clock.
ULPI Clock In Mode:
Connect this pin to VDDIO to configure 60MHz ULPI
Clock IN mode as described in Section 5.5.1.
The PHY asserts NXT to throttle the data. When the
Link is sending data to the PHY, NXT indicates when
the current byte has been accepted by the PHY.
ULPI bi-directional data bus. DATA[0] is the LSB.
ULPI bi-directional data bus.
ULPI bi-directional data bus.
