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