* 本程序为通过调试的源程序
*
* 功能描述:上电后系统等待用户输入登陆密码，用户可查询储存在24C02中的登陆密码(A键),也可修改登陆密码(B键),
* 当输入登陆密码后按D键，如果密码正确则进入系统。进入系统后6个数码管开始计时，同时循环播放4首音乐，发光二
* 极管也按预定流水灯程序循环闪动。此时按1-9键则播放第1-9首音乐。按0键则停止播放。按D键开始/停止音乐自动播
* 放。按*键开始/停止流水灯自动演示。按#键切换流水灯方案臘键则跳到下一首音乐，按A键、B键、C键则分别对时、分
* 、秒进行调节。
* 另外本程序集成了与PC通信的串口服务程序，所有按键的功能也可以通过PC机的控制软件实现。状态也可以反馈到此
* 控制软件上。
*
* 资源配置:Timer0用于为系统提供时基；Timer1用于音乐播放；Timer2用于串口波特率发生器。
* 3个中断源，其中两个为Timer0和Timer1中断，另一个为串口中断，主要完成与PC机的通信。
