Section 3.2
The S/PDIF input block will copy the incoming samples into memory in the order that
they occur in the input bitstream. The input bitstream is parsed and audio samples
are captured and packed as 32-bit words prior to being written to memory. The SPDIF
Input decoder always decodes the bi-phase encoded samples into binary prior to
transfer to memory. Refer to
sample sizes supported by the SPDIF Input module.

Raw capture mode: Subframe bits [31:0] inclusive are selected and stored. All
“biphase” encoded bits are decoded and a binary representation of the IEC60958
subframe is generated. The entire 32-bit binary number is then stored as one unit
in memory.
16-bit mode: The input samples are packed into 32-bit words consisting of two
16-bit samples per 32-bit word. This mode is compatible with the TM1100 and
PNX2700 Audio Out memory formats.
32-bit mode: For 17 through 24-bit audio, the samples are formatted into 32-bit
words and placed in memory at consecutive 32-bit addresses. For these sample
sizes, the sample is first combined with a programmable bitmask
