STM8L151 外中断频率计数时，中断服务程序中必须加延时吗？

dwwzl

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);

/* Cleat Interrupt Pending bit */

  EXTI_ClearITPendingBit(EXTI_IT_Pin2);

}

上面的Delay(0xFFFF); 是必须的吗？
如果没有它，中断会不停的进，造成计数不准

正点原子

不会吧...
