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.
Bits [31:28] Bits [27:20] Bits [19:8] Bits [7:0]
CAd = X ADC1 Node ID=05h
ADC2 Node ID=06h Verb ID = F06h Payload = 00h

CAd = X ADC1 Node ID=05h
ADC2 Node ID=06h Verb ID = 706h Payload = xxh
Bits Type Default Description
31:8 Read Only 000000h Reserved
7:4 Read/Write 0h
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.
3:0 Read/Write 0h
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.
