    In the project, you need to create a function of the form:
    extern "C" void ISR(void)
    {
        // timer16 is taken as an example
        if (TIM16_GET_ARRM_INT_STATUS(htimer16_1_))
        {
            // necessary actions
        }
        // reset timer interrupt flags
        TIM16_CLEAR_INT_MASK(htimer16_1_, 0xFFFFFFFF);
    }
    before that, be sure to connect the libraries:
    #include "mik32_hal_timer16.h"
    #include "mik32_hal_irq.h"
    #include "wiring_LL.h" */
