USBRXHUBPORTn is an 8-bit read/write register that, like USBRXHUBADDRn, only needs to be
written when a full- or low-speed device is connected to receive endpoint EPn via a high-speed USB
2.0 hub. This register provides the necessary transaction translation to convert between high-speed
transmission and full-/low-speed transmission. This register records the port of that USB 2.0 hub
through which the target associated with the endpoint is accessed. This information, together with
the hub address in USBTXHUBADDRn, allows the USB controller to support split transactions.

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.
