If the MCU target needs a reset circuit, please design the reset circuit according to the
diagram below.
Figure 4-2 Debugging Connector and Reset Circuit for Single Flash MCU
Pin 4 of the connector is used to connect to the reset circuit. Please design a switch K1
between the reset circuit and the reset pin (RSTX). Make sure to cut off K1 to stop the high
voltage flowing through the reset circuit during the debugging operation. Turn on K1 to
supply the reset circuit to the target MCU when the debugging operation is over.
