27.1.2 Hardware Overview
The S/PDIF is composed of two parts:
• The S/PDIF receiver extracts the audio data from each S/PDIF frame and places the
data in the S/PDIF Rx left and right FIFOs. The Channel Status and User Bits are
also extracted from each frame and placed in the corresponding registers. The S/
PDIF receiver provides a bypass option for direct transfer of the S/PDIF input signal
to the S/PDIF transmitter.
• For the S/PDIF transmitter, the audio data is provided by the processor through the
SPDIFTxLeft and SPDIFTxRight registers. The Channel Status bits are provided
