   10   The Audio Multiplexer (AMX) block can multiplex up to four input streams
   11   each of which can have maximum 16 channels and generate an output stream
   12   with maximum 16 channels. A byte RAM helps to form an output frame by
   13   any combination of bytes from the input frames.

   47       AMX has four inputs and one output. Accordingly ACIF (Audio Client
   48       Interfaces) port nodes are defined to represent AMX inputs (port 0
   49       to 3) and output (port 4). These are connected to corresponding
   50       ports on AHUB (Audio Hub).
