Peripheral operating requirements and behaviors
6.8.5 ULPI timing specifications
The ULPI interface is fully compliant with the industry standard UTMI+ Low Pin
Interface. Control and data timing requirements for the ULPI pins are given in the
following table. These timings apply to synchronous mode only. All timings are
measured with respect to the clock as seen at the USB_CLKIN pin.
