stm32使用串口空闲中断，仿真过程中打断或者程序停止运行时串口要是外部有数据geistm32发送，运行后不在进串口空闲中断
这种情况谁遇到过，

Translation with google:

When using a serial port idle interrupt in STM32, if the simulation is interrupted or the program stops running, and there is external data being sent via the serial port, the STM32 stops sending data after the program resumes running. Has anyone encountered this situation?
