Table 88
The USBD CFGVAL register provides the current selection of the configuration and
alternate setting done by the host. The SET_CONFIGURATION resets all settings to
Alternate Setting 0, i.e. the Control Endpoint 0.

15.7
For normal functionality, the following interrupts must be enabled:
all udc_tx_done- and udc_rx_done-interrupts of those endpoints and in the direction in
which they are used
udc_setup, udc_suspend, udc_suspendoff, udc_start of frame, udc_configval
optional interrupts are the EPEC-interrupt (this interrupt might only be used if SW needs
to have complete control over the contents of the fifos and always wants to keep track of
the status of the transmission) and the UDC_txwr- and UDC_rxrr-interrupts (which are
generated every time, a fifo in the USB-block is ready to accept data or receive-data

Resets the USB block including the transmit and
receive logic. The USB RESET does not reset the
USBCLC register. The USB reset must be active for
at least 10 clock cycles. The USB reset must always
be activated after the USB device is connected to
the USB
