//NAME:     main.asm                                                                         //
//DATE:     7/29/05                                                                          //
//PURPOSE:  ADSP-21369 EZ-KIT Test. Calls initialization routines then waits for interrupts  //
//                                                                                           //
//USAGE:    This file contains the main routine calls functions to set up the talkthrough    //
//          routine. It receives an input signal from the ADC via SPORT0A and outputs to     //
//          DAC's via SPORT1A, SPORT1B, SPORT2A, and SPORT2B.                                //
//                                                                                           //
