1.该例程测试定时器的捕获输入模式
2.测试方法，
（1）下载程序
(2)把USB转串口线连接到J8，打开串口调试助手，设置端口号，设置波特率为115200
（3）用一根排线连接到J25的LED4接口，接在GND.
(4) 在排线连接GND的一端，不停的拔出与插入。串口调试助手会显示定时计数器的值
（5）以下为打印出来的信息。（实验现象:当发生捕获中断的时候，显示定时计数器的值）

Hello NXP Semiconductors
Timer Capture Example
- MCU: LPC177x_8x
- Core: ARM CORTEX-M3
- UART Communication: 115200 bps
Use timer 0 to take a snapshot of the timer value when an input signal
on CAP0.0 transitions
