超级省电的时钟制作最省电时可达3mA [修正BUG] -

/***********************************************************************
作者：TZR
版本：CK3148 (ver2.0)
功能： 1 显示时间
　　　　2 显示日期
　　　　3 计算年份
　　　　4 闹钟功能
　　　　5 超小体积设计（电池最大……）
　　　　6 整点报时
　　　　7（重点改进点）超省电设计，正常工作电流在9~12mA之间，最省电时电流可达3mA!闹钟鸣响时电流在15mA~18mA左右。
　　　　8.增加省电模式，模式下耗电<3.3mA，数码管不显示，走时仍然继续，闹钟，整点报时仍然运行。（闹钟会中断省电模式）
日志：V1:实现走时功能，程序整体不稳定，闹钟和整点报时功能不正常。
　　　V1.2:修正闹钟和整点报时BUG，修正出现“0月0日的”BUG，修正年份显
V2:改进了程序，作品变得相当省电，耗电量相比之前下降一半，最省电时可达3mA.
V2.2:增加省电模式。修正程序稳定性差，整点报时不兼容“省电模式”的问题。
省电原理：LED显示屏低频闪烁，闪烁期间单片机进入空闲模式，使用定时器中断唤醒单片机，并产生时钟。
