程序描述：这个范例说明如何使用8051，以及汇编语言的程序连结，

当我们按下向上数的按钮之后，程序就会把0到9的共

阳7段显示器字型码存入AT93C46；如果我们按下向下

数的按钮之后，程序就会把9到0的共阳7段显示器字

型码存入AT93C46。

程序每一次重新开始执行时(Power on 或是Reset)，8051

会先从AT93C46当中读出最前面的10个位组，然后

就反复地将这10个位组的数据经由PORT 1送到1个

共阳七段显示器。*/-Procedure Descr iption: This example shows how to use the 8051, as well as links to assembly language programs, when we pressed up a few of the button, the program will bring a total of 0-9 yang seven segment display font yards into AT93C46　if we press Next down the number button, the program will bring a total of 9-0 Yang seven segment display font code into AT93C46.
