/* YSS225 initialization.

   This code was developed using DOSEMU. The Turtle Beach SETUPSND
   utility was run with I/O tracing in DOSEMU enabled, and a reconstruction
   of the port I/O done, using the Yamaha faxback document as a guide
   to add more logic to the code. Its really pretty weird.

   There was an alternative approach of just dumping the whole I/O
   sequence as a series of port/value pairs and a simple loop
   that output it. However, I hope that eventually I'll get more
   control over what this code does, and so I tried to stick with
   a somewhat "algorithmic" approach.
