stm8l151外中断脉冲计数时，在中断服务程序中必须添加延时吗？否则会频繁退出后又立即进中断！

有好的解决办法吗？

INTERRUPT_HANDLER(EXTI2_IRQHandler, 10)
{
  /* In order to detect unexpected events during development,
     it is recommended to set a breakpoint on the following instruction.
  */
 EXTI2_Decrement();
  Delay(0xFFFF);     // 此延时是必须的吗？
 /* Cleat Interrupt Pending bit */
  EXTI_ClearITPendingBit(EXTI_IT_Pin2);
}
