1. Function description
    1. After TIM2 CH1 CH2 CH3 CH4 reaches the CC value, correspondingly pull down the IO level of PC6, PC7, PC8, and PC9
2. Use environment
	Software development environment: KEIL MDK-ARM V5.34.0.0
    Hardware development environment:
         N32G05x series:
            Developed based on the evaluation board N32G05xRBQ7_STB V1.0
         N32G05x series:
            Developed based on the evaluation board N32G05xRBL7_STB V1.0
3. Instructions for use
    System Configuration;
        1. Clock source:
                    HSI=8M,SYS CLK=64M,TIM3 CLK=32M
        2. Interruption:
                    TIM2 compare interrupt is turned on
        3. Port configuration:
                    PC6 is selected as IO output
                    PC7 is selected as IO output
                    PC8 is selected as IO output
                    PC9 is selected as IO output
        4. TIM:
                    TIM2 configures the comparison value of CH1, CH2, CH3, CH4, and turns on the comparison interrupt
    Instructions:
        1. After compiling, turn on the debug mode, and use an oscilloscope or logic analyzer to observe the waveforms of PC6, PC7, PC8, and PC9
        2. After the timer enters the CC1 CC2 CC3 CC4 interrupt, it will correspondingly pull down the IO of PC6 PC7 PC8 PC9
