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; } |
