When RST MCU STC89C51 outputs and inputs a high level and supports two machine cycles, when the output remains at a high level, the operation is run in a computer system. The MCU is in the circulating discharge state.<br>In the simplest automatic reset circuit, when it is switched on, the capacitor of the external discharge circuit is charged and discharged. When the growth time of VCC is less than 1 millisecond, you can reset it automatically when the power is turned on.<br>In addition to disconnecting the power, sometimes you need to manually reset the button. This design should use the manual reset button. There are two types of manual reset: horizontal and pulse mode. Among them, RST(<br>
