Response Format:
The S/PDIF IEC Control (SIC) bits are supported in one of two ways. In the first case referred to as “Codec
Formatted SPDIF,” if a PCM bit stream of less than 32 bits is specified in the Converter Format control,
then the S/PDIF Control bits, including the “V,” “PRE,” “/AUDIO,” and other such bits are embedded in the
stream by the codec using the values (SIC bits) from the Digital Converter Control.
In the second case referred to as “Software Formatted (or Raw) SPDIF,” if a 32-bit stream is specified in
the Converter Format control, the S/PDIF IEC Control (SIC) bits are assumed to be embedded in the
stream by software, and the raw 32-bit stream is transferred on the link with no modification by the codec.
However, the codec must properly interpret the Sync Preamble bits of the stream and then send the ap-
propriately coded preamble. The IEC60958 specification, Section 4.3, “Preambles,” defines the pream-
bles and the coding to be used. Software will specify the “B,” “M,” or “W” (also known as “X,” “Y,” or “Z”)
preambles by encoding the last four bits of the preamble into the Sync Preamble section (bits 0-3) of the
frame. The codec must examine the bits specified and encode the proper preamble based on the previous
state. The previous state is to be maintained by the codec hardware.
