F2806x USB Hardware
The USB controller requires a total of three signals (D+, D-, and
VBus) to operate in device mode and two signals (D+, D-) to operate
in embedded host mode
VBus implemented in software using external interrupt or polling
GPIOs are NOT 5V tolerant
Make them tolerant using 100k and internal device ESD diode clamps
Note: (1) VBus sensing is only required in self-powered applications
(2) Device pins D+ and D- have special buffers to support the high speed requirements
of USB; therefore their position on the device is not user-selectable
