MSC-51系列单片机内有128B或256B的RAM数据存储器，对一般应用场合，内部 RAM可以满 足系统对数据存储器的要求，但对需要大容量数据缓冲器的应用系统（如数据采集系统），仅片内的RAM存储器往往不够用，这种情况下，就需要在单片机外部扩展数据存储器。 MSC-51与外部数据存储器的一般连接方法：外部数据存储器的高8位地址由P2口提供，低8位地址线接地址锁存器的输出端。外部RAM的读、写控制信号分别接MCS-51的 、 。外部RAM的片选信号可由P2口未用的地址线的剩余口线以线选方式或译码方式提供。 随机存贮芯片（RAM）HM62256的存贮量为32KB，地址线有(A0～A14)，是单片机应用系统中最常见的数据存储器 -err

总测试程序，不仅可以测定其转速的信息，而且可以用于测定其报警信息的内容。可联合以上的程序进行调试。-The total test procedure can not only determine his speed information, but can be used for the determination of the contents of its report to the police information. The above procedures can be combined for debugging.

该时钟以24小时制显示时间，并可显示2000年至2049年之间的任何日期及星期，日期与时间经按键可相互切换，可输入8个闹钟时间设置，每个闹钟设置包括响铃的时间（小时与分钟）、对工作日有效还是对周末有效的标志，以及本项设置是否启用的标志等三部分。这8个闹钟设置均保存在EEPROM中，即使掉电也不用重新输入。-The 24-hour clock to display time, and shows from 2000 to 2049 and any date between the weeks, the date and time as may be mutually switch button, enter the eight alarm time settings, each set including the ringing of an alarm clock Duration (hours and minutes), the effective working days or weekends effective road signs, as well as whether or not to enable this setting, such as a symbol of three parts. This 8 alarm settings are stored in EEPROM, even brown-out do not have to re-enter.
