This command is used to set the USB assigned address in the DcAddress register and
enable the USB device. The DcAddress register bit allocation is shown in
A USB bus reset sets the device address to 00H (internally) and enables the device. The
value of the DcAddress register (accessible by the microcontroller) is not altered by the
bus reset. In response to the standard USB request, Set Address, the firmware must issue
a Write Device Address command, followed by sending an empty packet to the host. The
new device address is activated when the host acknowledges the empty packet.

Description
A logic 1 indicates an enabled FIFO with allocated memory. A
logic 0 indicates a disabled FIFO (no bytes allocated).
This bit defines the endpoint direction (0 = OUT, 1 = IN); it also
determines the DMA transfer direction (0 = read, 1 = write).
A logic 1 indicates that this endpoint has double buffering.
A logic 1 indicates an isochronous endpoint. A logic 0 indicates a
bulk or interrupt endpoint.

A logic 1 enables the device.
This field specifies the USB device address.
