Application scope:
1. Used as a square wave signal generator produces a square wave signal for the experimental development use.
2. A square wave signal is used to produce a stepper motor-driven drive.
3. Produce the adjustable pulse for MCU use.
4. Generates the adjustable pulse to control the associated circuits.
