刚刚接触STM8A，不是很懂。
请问在中断里的return是什么作用？？？
请老师们指点。。。。。
程序如下：
/**
* @brief USART RX interrupt routine.
* @par Parameters:
* None
* @retval void None
* @par Required preconditions:
* None
* @par Called functions:
* None
*/
@near @interrupt void USART_RX_IRQHandler (void)
{
/* In order to detect unexpected events during development,
it is recommended to set a breakpoint on the following instruction.
*/
return;
} |
