1、功能说明
    此示例描述了通过SHRTIM输出PWM波形


2、使用环境

    软件开发环境：KEIL MDK-ARM V5.34
                  IAR EWARM 8.50.1 
    芯片支持：
        N32H785
        N32H785xxxEC
        N32H787


3、使用说明

    系统配置
        1、 时钟源：
            HSE=25M,SHRPLL=312.5M,M7 clock = 600M,  
            SHRTIM clock(SHRPLL) = 312.5M，High-resolution clock = 10GHz。
        2、 端口配置：
            PC6选择为SHRTIM的TA1的输出
        3、SHRTIM：
            TA1输出，连续计数模式

    使用方法：
        1、将78x的GPIO的LedBlink demo和当前CM4的工程程序分别编译后下载到开发板并复位运行;
        2. 用示波器或者逻辑分析仪观察SHRTIM的TA1的输出波形，频率200KHz，占空比50%

2. Development environment

    Software development environment: KEIL MDK-ARM V5.34
                  IAR EWARM 8.50.1 
    Chip support:
        N32H785
        N32H785xxxEC
        N32H787


3. How to use

    System configuration
        1. Clock source:
            HSE=25M,SHRPLL=312.5M,M7 clock = 600M,  
            SHRTIM clock (SHRPLL) = 312.5M, High-resolution clock = 10GHz.
        2. Port configuration:
            PC6 is selected as the output of TA1 of SHRTIM
        3. SHRTIM:
            TA1 output, continuous counting mode

    Usage:
        1. Compile the LedBlink demo for GPIO of 78x and the current CM4 project program separately, download them to the development board, and reset to run;
        2. Observe the output waveform of SHRTIM's TA1 using an oscilloscope or logic analyzer, with a frequency of 200KHz and a duty cycle of 50%

4. Attention
    None
