// DESCRIPTION
//   This file contans mostly hardware related defintions (e.g. I/O ports and
// bits, clock speeds, memory sizes, etc) for the MP3 player project.
//
//   IMPORTANT - there is a companion to this file, PLAYER.INC, which contains
// a duplicated subset of this information for the convenience of the assembly
// language modules.  IF YOU CHANGE THIS FILE, YOU'LL WANT TO CHANGE PLAYER.INC
// TOO!  Sorry about this, but I know of no better way to handle it!
//
// REVISION HISTORY:

// 15-May-05    RLA     New file.
