Notes: 1. VBUS interrupts in the USB module cannot be detected in power-down mode or
in the USB module stop state.
2. In bus-powered mode, power is applied after the USB cable has been connected.
Accordingly, immediately after completing the power-on reset, initialization (14.5.1), clearing all FIFOs,
and system preparation, enable the D+ pull-up by the port 36 (P36) and cancel the UDC core reset state.
