int main(void){
    /* Initialize the system    */
    iniconf();
 
    /* Initialize goblal variables    */
    count = 0;
    ticks = 0;
    tone = 0;
 
    while(1){
        delay(50);
        PORTB = (PORTB & 0x0f) | 0xf0; //SETUPNIB;
        delay(50);
        PORTB = (PORTB & 0x0f);        //RESETUPNIB;
    }
}
