/* Port addresses and bit fields for the Media Vision Pro AudioSpectrum
 * second generation sound cards.
 *
 * Feel free to use this header file in any application you create that
 * has support for the Media Vision Pro AudioSpectrum second generation
 * sound cards. Other uses prohibited without prior permission.
 *
 * - cmetz (at) thor.tjhsst.edu
 *
 * Notes:
 *
 * -	All of these ports go into the MVD101 multimedia controller chip,
 *	which then signals the other chips to do the actual work. Many
 *	ports like the FM ones functionally attach directly to the
 * 	destination chip though	they don't actually have a direct connection.
 * -	The PAS2 series cards have an MVD101 multimedia controller chip,
 * 	the original PAS cards don't. The original PAS cards are pretty
 * 	defunct now, so no attempt is made here to support them.
 * -	The PAS2 series cards are all really different at the hardware level,
 * 	though the MVD101 hides some of the incompatibilities, there still
 * 	are differences that need to be accounted for.
