This source control register is divided into two parts (MOSSRC and MOPSRC). This design allows some
additional functionality such as jitter cleaning. To clean the clock jitter of the HDMI receiver output, the HDMI
receiver S/PDIF output is connected to the DIX9211 S/PDIF input, and the HDMI receiver I²S outputs
(BCK/LRCK/DATA) are connected with the DIX9211 PCM input port.
