Receiver User Data Register (RUI)

The register stores the U-bit data received through the Renesas SPDIF. Because U-bit data is stored in a sequence of
subframes 1 and 2 starting at the LSB, you need to read the data on a 16-frame basis. For the contents of the user bytes
refer to the appropriate standard for the device in use.
