利用下面介绍的方法,可对RAM的可靠性进行动态检查。在TP801—A单板机上可检查1K×4位的2114静态读写存贮器;在TP801—B单板机上可检查6116(2K×8位)静态读写存贮器。将待查RAM(2K字节)插入以2000H单元为起始地址的插座中,用下面的检查程序进行检查。该程序可反复循环运行,可根据需要决定动态检查的时间。如果检查时间到,RAM的读写一直不出错,即可按复位键RESET或按返回监控键MON,停止程序的运行。
Using the method described below, you can dynamically check the reliability of RAM. On the TP801-A single-board machine can check 1K × 4 2114 static read and write memory; TP801-B single-board machine can check 6116 (2K × 8) static read and write memory. Insert the RAM to be checked (2K bytes) into the socket starting from Unit 2000H and check with the following checkout procedure. The program can be run repeatedly, according to the need to decide the time of dynamic inspection. If the check time, RAM read and write has been wrong, you can press the reset button RESET or press the monitor key MON, to stop the operation of the program.
