   10   The Audio Demultiplexer (ADX) block takes an input stream with up to
   11   16 channels and demultiplexes it into four output streams of up to 16
   12   channels each. A byte RAM helps to form output frames by any combination
   13   of bytes from the input frame. Its design is identical to that of byte
   14   RAM in the AMX except that the data flow direction is reversed.

   47       ADX has one input and four outputs. Accordingly ACIF (Audio Client
   48       Interface) port nodes are defined to represent ADX input (port 0)
   49       and outputs (ports 1 to 4). These are connected to corresponding
   50       ports on AHUB (Audio Hub).
