                             Sample Description
================================================================================
功能描述：
该样例演示了CCT的输入捕获功能，PA2为输入捕获引脚，捕获上升沿并计算两个上升沿宽度
之间的宽度。

Function descriptions:
This sample demonstrates the input capture function of the CCT. PA2, PA3 and PA6 
are the input capture pins, which capture the rising edge and generate interrupts.
================================================================================
测试环境：
测试用板：DPM32M030_REV_A
MDK版本： 5.28

Test environment:
Test board: DPM32M030_REV_A
MDK Version: 5.28
================================================================================
使用步骤：
1. 编译下载程序到MCU，并运行。
2. 从PA2输入待捕获的波形

Example execution steps:
1. Compile and download the program to MCU, and run it.
2. Input the waveform to be captured from PA2.
================================================================================
注意事项：
CCT引脚如下：
CCT0_CH0  -> PA2

Notes:
The CCT pins are as follows:
CCT0_CH0  -> PA2
