This bit has no effect when UIDE is one (USB_ID input pin activated).
0: The module is in USB host mode.
1: The module is in USB device mode.
This bit can be written even if USBE is zero or FRZCLK is one. Disabling the USBB (by writing a zero to the USBE bit) does not
0: The USB mode (device/host) is selected from the UIMOD bit.
1: The USB mode (device/host) is selected from the USB_ID input pin.
