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
with respect to the clock as seen at the USB_CLKIN pin on the MCF5445x. The ULPI PHY is the source of the 60MHz clock.

The USB controller requires a 60-MHz clock, even if using the on-chip FS/LS transceiver
instead of the ULPI interface. In this case, the 60-MHz clock can be generated by the PLL
or input on the USB_CLKIN pin.
