1. 完成时／分／秒的依次显示并正确计数，利用六位数码管显示； 2. 时／分／秒各段个位满10正确进位，秒／分能做到满60向前进位，有系统时间清零功能； 3. 定时器：实现整点报时，通过扬声器发出高低报时声音； 4. 时间设置，也就是手动调时功能：当认为时钟不准确时，可以分别对分／时钟进行调整； 5. 闹钟：实现分/时闹钟设置，在时钟到达设定时间时通过扬声器响铃。有静音模式。 -1. Completed/min/sec display and correctly followed by counting, using six digital tube display 2. When/min/sec in the paragraphs of the correct 10-bit binary full, s/sub can do to advance the age of 60-bit, systematic function of the time cleared 3. timers: realize the whole point of time, by the time the level of sound from loudspeakers 4. time settings, which is manually adjusted when the function: When the clock does not consider accurate, they can respectively sub/clock adjustments 5. alarm clock: the realization of sub-/ when the alarm clock settings, settings in the clock arrival time ringing through the loudspeakers. There are silent mode.
