Description
Reserved
Stream Number (SN): This field is written by
software to indicate the stream number used by
the Output Converter. “0h” is stream 0, “1h” is
stream 1, etc.
By convention, stream 0 is reserved and unused
so that converter whose stream number has
been reset to “0h” does not unintentionally
decode data not intended for them.
Lowest Channel Number (LCN): This field is
written by software to indicate the lowest channel
used by the Output Converter. The stereo con-
verter will use this LCN value plus 1 for its left
and right channel.
