The debugging serial port is generally composed of a UART module and different types of physical layer interface chips such as RS232 or RS 485. The invention adopts a physical layer interface chip of the UART-to-USB interface, thus realizing the unification of external physical interface forms of the debugging serial port unit and the USB storage unit.
The analog switch unit is used for switching between the debugging serial port unit and the USB storage unit back and forth according to requirements and realizing input and output from the same panel port. The control unit is used for controlling various enabling signals, such as gating signals for controlling the analog selector switch, so as to select and debug the data signals of the serial port unit or the data signals of the USB storage unit.

The UART module is added with a physical layer interface chip to form a debugging serial port. The USB storage unit 302 is used to implement an external USB memory function. The panel USB port 303 is an external multiplexing interface of the debug serial port unit and the USB storage unit, and defines a data signal pin and a power signal pin. The analog switch unit 304 is used to gate and debug the data channel of the serial port unit or the USB memory unit according to the requirement.
The current limit switch unit 305 is used to turn on or off the power signal provided by the device to the panel USB port. When the panel USB port is used as a debugging serial port, the USB port belongs to slave equipment, and a port power supply is provided by an upper computer in a master equipment state through a USB cable, so that the power supply provided by the equipment to the panel USB port is cut off by closing a current-limiting switch; when the panel USB port is used as a storage interface, the USB port belongs to a master device, the external USB memory is in a slave device state, and the port power is provided by the device in the master device state, so that the power provided by the device for the panel USB port is turned on by turning on the current-limiting switch.

And after the functional unit B is executed, the analog change-over switch is gated to the unit A again. The unit A and the unit B can be a debugging serial port unit or a USB storage interface unit.
