Stm32f072 external interrupts more than one

Also I have checked in .s file , both interrupts are enabled, and also at power on, i have enabled interrupt as risinf edge triggered.​

​

Both interrupts come independently, but if I run two interrupts combined ly, only single interrupt comes.​

Read out and check/post relevant GPIO, SYSCFG, EXTI and NVIC registers content. Check in disasm, if the proper ISR vector is inserted in the respective position in the vector table.

Ok,

Initialisation part as below:-

------------------------------------------------------------------------------------------------------------------

interruptEnable (GPIOA_BASE,GPIO_Pin_0,INT_RISE); //  BMS Alert-Lower

 interruptEnable (GPIOC_BASE,GPIO_Pin_13,INT_RISE); //  BMS Alert-Upper

------------------------------------------------------------------------------------------------------------------

==================================================================

Below is ISR i wrote for Both Pin Interrupt:-

------------------------------------------------------------------------------------------------------------------

void EXTI0_1_IRQHandler(void)

{

 if(EXTI_GetITStatus(EXTI_Line0) != RESET)

 {

  if (isrtimeout[0] > 20)

  {

   alertFlag[0] = 1;

   isrtimeout[0] = 0;

   alerttimeout[0] = 0;   

  }

  EXTI_ClearITPendingBit(EXTI_Line0);

 }

}

void EXTI4_15_IRQHandler (void)

{

 if(EXTI_GetITStatus(EXTI_Line13) != RESET)

 {

   if (isrtimeout[1] > 20)

  {

   alertFlag[1] = 1;

   isrtimeout[1] = 0;

   alerttimeout[1] = 0;   

  }

  EXTI_ClearITPendingBit(EXTI_Line13);

 }  

}

Below is .s File snap only :-

------------------------------------------------------------------------------------------------------------------

Regarding debugger with Hardware i can do in normning as my hardware is @ officeand am at home currentlly.

Thanks
