1. Function description
    1. TIM3 uses the CH1 CH2 CH3 CH4 CC value to generate a timing interrupt and flip the IO level
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,TIM2 CLK=64M
        2. Port configuration:
                    PC6 is selected as the CH1 output of TIM3
                    PC7 is selected as the CH2 output of TIM3
                    PC8 is selected as the CH3 output of TIM3
                    PC9 is selected as the CH4 output of TIM3
        3. TIM:
                     TIM3 CH1 CH2 CH3 CH4 has the same period, and the duty cycle is not equal
    Instructions:
         1. After compiling, turn on the debug mode, use an oscilloscope or logic analyzer to observe the waveforms of TIM3 CH1, CH2, CH3, CH4
         2. After the program runs, 4 PWM signals with equal period and different duty cycle are generated
4. Matters needing attention
