P89V51RD2系列芯片是具有串口下载功能（ISP）和在KEIL中进行调试的功能（SOFTICE）。 新的芯片是ISP功能，通过FlashMagic 软件可以设置其为SOFTICE功能。 但要想回到ISP功能，则没有现成的好办法，只有通过编程器了。 但现在可以通过这个程序来恢复其ISP功能（禁止SOFTICE）。-P89V51RD2 series with the serial port chip is the ability to download (ISP) and the KEIL for debugging feature (SOFTICE). The new chip is the ISP, through FlashMagic software can be set to SOFTICE its function. However, to return to the ISP, there is no ready-made good, and that only through a programmer. But now through this procedure to restore its ISP (Prohibition SOFTICE).

本系统采用MSC-51系列单片机ATSC51和可编程并行I/O接口芯片8255A为中心器件来设计交通灯控制器，实现了能根据实际车流量通过8051芯片的P1口设置红、绿灯燃亮时间的功能；红绿灯循环点亮，倒计时剩5秒时黄灯闪烁警示（交通灯信号通过PA口输出，显示时间直接通过8255的PC口输出至双位数码管）；车辆闯红灯报警；绿灯时间可检测车流量并可通过双位数码管显示。本系统实用性强、操作简单、扩展功能强。 -The system uses MSC-51 series single-chip ATSC51 and programmable parallel I/O interface chip 8255A-centric device designed to control traffic lights, can be achieved in accordance with the actual traffic flow through the P1 port 8051 chip set red, green fuel Liang function of time traffic light cycle, the countdown five seconds left when the yellow light flashing warning (traffic lights through the PA output signal indicates the time directly through the PC port output 8255 to double-digits) vehicle alarm闯红灯 green time traffic flow can be detected through a double-digital display. The system practical, simple and strong extensions.
