In mode 0b001 (MPEG ID selected), the MPEG audio
stream is assumed to be MPEG-1 audio or MPEG-2
audio without extensions. The audio stream comes in a
single ID programmed in the Audio Stream ID field
above.
In mode 0b100 (All MPEG Audio IDs), no audio streams
are filtered out. Use this mode when you know that only
one audio stream is in the incoming bitstream.
In mode 0b101 (MPEG audio multichannel with
extension), the main audio stream ID is programmed in
the Audio Stream ID field above and the extension is
programmed in the MPEG Audio Extension Stream ID
field in Register 124
