power state transition). Within this type of node, this field will be the lower power consuming state of either
a) the PS-Set field of the currently referenced node or b) the PS-Set field of the Audio Function Group
node under which the currently referenced node was enumerated (is controlled).

Description
Reserved
Stream Number (SN): This field is written by
software to indicate the stream number used by
the Input 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 Input Converter. The stereo con-
verter will use this LCN value plus 1 for its left
and right channel.
6.5.13 Converter Format
Get Parameter Command Format:
Bits [31:28]
CAd = X
Bits [27:20]
ADC1 Node ID=05h
ADC2 Node ID=06h
Bits [19:8]
Verb ID = A00h
Bits [7:0]
Parameter ID = 00h
Set Parameter Command Format:
Bits [31:28]
CAd = X
Bits [27:20]
ADC1 Node ID=05h
ADC2 Node ID=06h
Bits [19:8]
Verb ID = 2xxh
Bits [7:0]
Parameter ID = xxh
Response Format:
Bits [15:0] must be programmed by software with the same value programmed into the Stream Descriptor,
so that the data format being transmitted on the link matches what is expected by the consumer of the
data.
