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 six registers used for USB functions.
A.5.1.1 USB Function Address Register (USBFADR 鈥?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 is 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.
