USB OTG like connector implementation (PDF!):
The USB OTG (On-The-Go) is an interface to communicate with portable USB devices.
In the SAM9x5 Series (SAM9G15/G25/G35/X25/X35) and SAMA5D3x products, the USB host and device share one transceiver. The shared USB transceiver can be controlled either by the USB Host Port Controller or by the USB Device Controller. This configuration allows to emulate a “USB OTG like” connector. The purpose of this document is to help the developers to implement this kind of USB OTG.
