计数器实验 *

* 定时器1工作于16位计数模式，记录外部脉冲的个数； *

* 定时器0工作于定时模式，用于进行动态扫描显示 *

* *

* 此程序可用按键AN4来演示，但是由于按键有抖动现象，所以每按一次*

* 有可能产生多次计数脉冲 *

*-Timer 1 Counter** Experimental work on 16 count mode, recording the number of external pulse ** Timer 0 in the regular pattern of work for the dynamic scan revealed**** This procedure can be used to demonstrate key AN4, but Since the keys have a jitter phenomenon, so every time** may have multiple pulse count**
