22.7.12 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.
