The USBC mode (device or host) can be detected by the USB_ID pin or selected by writing to
USBCON.UIMOD. This allows the USB_ID pin to be used as a general purpose I/O pin even
when the USBC interface is enabled.
The ID Transition Interrupt (IDTI) bit in USBSTA is set on each transition of the ID bit, i.e. when a
Mini-A plug (host mode) is connected or disconnected. This does not occur when a Mini-B plug
in device mode is connected or disconnected.
The USBSTA.ID bit is operational regardless of whether the USBC is enabled or not.
