A.5.1 USB Registers
This section describes the memory-mapped registers used for control and operation of the USB functions.
This section consists of 6 registers used for USB functions.
A.5.1.1 USB Function Address Register (USBFADR − Address FFFFh)
The USB function address register contains the current setting of the USB device address assigned to the
function by the host. After power-on reset or USB reset, the default address will be 00h. During
enumeration of the function by the host, the MCU should load the assigned address to this register when
a USB Set_Address request is received by the control endpoint.
