USBTXHUBADDRn is an 8-bit read/write register that, like USBTXHUBPORTn, only must be written
when a USB Device is connected to transmit endpoint EPn via a USB 2.0 hub. This register records
the address of the USB 2.0 hub through which the target associated with the endpoint is accessed.
Note: USBTXHUBADDR0 is used for both receive and transmit for endpoint 0.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Hub Address
This field specifies the USB bus address for the USB 2.0 hub.
