//NAME:     main.c (Block-based Talkthrough)
//DATE:     7/29/05
//PURPOSE:  Talkthrough framework for sending and receiving samples to the SPDIF peripherals.
//
//USAGE:    This file contains the main routine calls functions to set up the talkthrough
//          routine. It receives an input signal from the SPDIF Rx via SPORT0A and outputs
//          to DAC's via SPORT3A.
//

void main(void)

    // SPORT0 interrupt calls TalkThroughISR
    interrupt (SIG_SP0,TalkThroughISR);
    
    //Initialize PLL to run at CCLK= 331.776 MHz & SDCLK= 165.888 MHz.
    InitPLL_SDRAM();

    // Need to initialize DAI because the sport signals need to be routed
    InitSRU();

    // Set up SPDIF transmitter and receiver.
    InitSPDIF();

    // Finally setup the sport to receive / transmit the data
    InitSPORT();

    // Be in infinite loop and do nothing until done.
    for(;;)
