We are using above mentioned device (STM32F765BI) MCU in customized board. I need some clarification on USB interfaces
1. How many Full speed & High speed USB interface available in this device .
2. As per reference manual it has two USB PHY (OTG FS and OTG HS), So can I use one USB interface in full speed & another USB interface in high speed mode without using any external phy (ULPI interfaced PHY).
3. some pins are conflicting with USB_ID,USB_VBUS & SOF pins, So I want to know whether these pins can be avoidable ( want to use both two USB interfaces) and corresponding setting can be done by software.
4. What is maximum possible frame size in both USB HS & FS modes
