微机实验硬件三 （供学习）1、按实验手册图3-1连接好电路，将计数器0设置为方式0，计数器初值为N(N≤0FH)，用手动逐个输入单脉冲，编程使计数值在屏幕上显示，并同时用逻辑笔观察OUT0电平变化(当输入N+1个脉冲后OUT0变高电平)。
2、按实验手册图3-2连接电路，将计数器0、计数器1分别设置为方式3，计数初值设为1000，用逻辑笔观察OUT1输出电平的变化(频率1HZ)。
-Experiment of microcomputer hardware three (for learning) 1, according to the Experimental Manual of 3-1 circuit connected, the counter is set to 0 means 0, counter initial value for N (N ≤ 0FH), manual input one by one single pulse, programming the count value is displayed on the screen, and at the same time a logical pen observation of OUT0 level change (when the input N+1 pulse OUT0 high level).
2, according to the laboratory manual 3-2 connection circuit, the counter 0, counter 1 is set to mode 3, counting the initial value is set to 1000, to observe the changes of OUT1 output level with logical pen (1HZ).
