Register 1: USB Device Functional Address (USBFADDR), offset 0x000
USBFADDR is an 8-bit register that contains the 7-bit address of the Device part of the transaction.
When the USB controller is being used in Device mode (the HOST bit in the USBDEVCTL register
is clear), this register must be written with the address received through a SET_ADDRESS command,
which is then used for decoding the function address in subsequent token packets.
Important: See the section called “Setting the Device Address” on page 870 for special
considerations when writing this register.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
