• USB controller enable
• Set address
Before any USB transaction, the 48 MHz required by the USB controller must be correctly
generated (See “Clock Controller” on page 14.).
The USB controller will be then enabled by setting the EUSB bit in the USBCON register.
After a Reset or a USB reset, the software has to set the FEN (Function Enable) bit in the
USBADDR register. This action will allow the USB controller to answer to the requests sent
at the address 0.
When a SET_ADDRESS request has been received, the USB controller must only answer
to the address defined by the request. The new address will be stored in the USBADDR reg-
ister. The FEN bit and the FADDEN bit in the USBCON register will be set to allow the USB
controller to answer only to requests sent at the new address.
