USB Electrical Specifications
This section describes the electrical information of the USBOTG port. The OTG port supports both serial
and parallel interfaces.
The high speed (HS) interface is supported via the ULPI (Ultra Low Pin Count Interface). Figure 84
depicts the USB ULPI timing diagram, and Table 63 lists the timing parameters.
