18.5 Register Descriptions

18.5.1 USB Device Functional Address Register (USBFADDR), offset 0x000

The USB function address 8-bit register (USBFADDR) 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.
Mode(s): OTG B or Device
For special considerations when writing this register, see the Setting the Device Address in
Section 18.2.1.1.4.
