摘要
ＭＣ１４６８１８是一种新型的实时时钟／日历集成电路，功能很强．本文介绍了一种利用微控制器和ＭＣ１４６８１８设计的显示控制屏的硬逻辑设计和软件功能设计．实现了准确、不怕掉电的可控时钟和较好的时控电路系统．
MC146818 is a kind of new real time clock/calendar integrated circuit and it has a powerful function. This paper introduce a type of hardware logical design and software functional design of display control screen by making use of micro-controller and this integnted circuit. They bring about the better system of the control circuit and the exact controlled-clock without turning off the power.
