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.
