USB device address register
Initially when a device is connected to the USB, it responds to the host on address 0. Using
the Set_Address request, the host assigns a unique address to the device. The firmware
writes this address to the USB Device Address register (see Table 100), and subsequently
the SIE only responds to transactions on that assigned address. This assigned address is in
effect until the device or an upstream hub is disconnected from the USB, the host issues a
USB Reset, or the host shuts down. The address register is cleared with a Hardware
RESET. When a USB RESET is detected, the address register should be cleared.
