Ответ: Весь код инициализации VIC:
// Setup interrupt controller.

// Disable all interrupts

VICDefVectAddr = (unsigned int)&DefDummyInterrupt;
// Setup timer callback function.
VICIntSelect=0x0; // Timer 0&1 select as IRQ.
VICVectAddr0 = (unsigned int)&Timer1Interrupt;
VICVectCntl0 = 0x20 | VIC_TIMER1; // Enable vector interrupt for timer 1.

VICVectCntl1 = 0x20 | VIC_TIMER0; // Enable vector interrupt for timer 0.
VICIntEnable = 0x30; // Enable timer 0&1 interrupt.
