     In the project, you need to create a function of the form:
     extern "C" void ISR()
     {
-        // timer16 is taken as an example
-        if (TIM16_GET_ARRM_INT_STATUS(htimer16_1_))
+        if (EPIC_CHECK_TIMER16_1())
         {
-            // necessary actions
+            // 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);
         }
-        // reset timer interrupt flags
-        TIM16_CLEAR_INT_MASK(htimer16_1_, 0xFFFFFFFF);
     }
