Description

31:8

Read Only

000000h

Reserved

7:4

Read/Write

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.

3:0

Read/Write

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.
