Digital Converter Control
Get Parameter Command Format:
** Note: Address F0Eh is not supported.
Set Parameter Command Format:
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,” on an input PCM stream of less than 32 bits, the codec strips off the SIC bits before
transferring the samples to the system and puts them in the Digital Converter Control for later software
access.
In the second case, referred to as “Software Formatted (or Raw) SPDIF,” on a 32-bit input stream, the
entire stream is transferred into the system without the codec stripping any bits. However, the codec must
properly interpret the Sync Preamble bits of the stream and then send the appropriately coded preamble.
The IEC 60958 specification, Section 4.3, “Preambles,” defines the preambles 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.
