ARM, RISC-V контроллеры

Вопрос по прерываниям Люди, что я делаю нетак (не надо говорить, что все)? void InitInterrupt(void(*ptrfTimer0)(), void(*ptrfUart0)(), void(*ptrfI2C)(), void(*ptrfSPI)(), void(*ptrfUART1)()) { // Setup interrupt controller. __VICProtection = 0; // Disable all interrupts __VICIntEnClr = 0xffffffff; __VICIntSelect &= ~(VIC_TIMER0_bit | VIC_UART0_bit | VIC_SPI_bit | VIC_I2C_bit | VIC_UART1_bit); // IRQ on Timer0 and UART0 line. __VICVectAddr0 = (unsigned int)ptrfTimer0; //Channel 0 of VIC - TimerO interrupt __VICVectAddr1 = (unsigned long)ptrfUart0; //Channel 1 of VIC - UARTO interrupt __VICVectAddr2 = (unsigned int)ptrfUART1; __VICVectAddr3 = (unsigned int)ptrfSPI; __VICVectAddr4 = (unsigned int)ptrfI2C; __VICVectCntl0 = 0x20 | VIC_TIMER0; // Enable vector interrupt for Timer0 on channel 0 and set his type. __VICVectCntl1 = 0x20 | VIC_UART0; // Enable vector interrupt for UART0 on channel 1 and set his type. __VICVectCntl2 = 0x20 | VIC_UART1; // Enable vector interrupt for UART0 on channel 1 and set his type. __VICVectCntl3 = 0x20 | VIC_SPI; __VICVectCntl4 = 0x20 | VIC_I2C; __VICIntEnable |= (VIC_TIMER0_bit | VIC_UART0_bit | VIC_UART1_bit | VIC_SPI_bit | VIC_I2C_bit); // Enable Timer0 and UART0 interrupt. } После такой инициализации прерываний они не срабатывают. P.S. __enable_interrupt() делаю. Среда разработки IAR.
