                             Sample Description
================================================================================
功能描述：
该样例演示了CCT的输入捕获功能，PA3为输入捕获引脚，捕获上升降沿，计算两个上升沿之间的
宽度并打印到串口。

Function descriptions:This example demonstrates the input capture function of CCT, 
PA3 is the input capture pin, capturing the rising and falling edges, and 
calculating the distance between two rising edges Width and print to serial port.
================================================================================
测试环境：
测试用板：DPM32M087RBTx_EVB V1.0
MDK版本： 5.28

Test environment:
Test board: DPM32M087RBTx_EVB V1.0
MDK Version: 5.28
================================================================================
使用步骤：
1. 编译下载程序到MCU，并运行。
2. 从PA3输入待捕获的波形，串口实时打印捕获宽度。

Example execution steps:
1. Compile and download the program to MCU, and run it.
2. Input the waveform to be captured from PA3, and print the capture width in 
real-time through the serial port.
================================================================================
注意事项：
CCT引脚如下：
CCT0_CH1  -> PA3


Notes:
The CCT pins are as follows:
CCT0_CH1  -> PA3
