//一、程序说明:
//1, 24LC02器件地址是1010000R/W.
//2, 数组写入24LC02采取页写方式.
//3, 数组code从24LC02读出时采取自由读方式.
//4, 采用4.00M晶体。
//5,采用软件I2C。
//二、硬件连接:
//1, SDA------->23 pin.(当然你可以任意选择脚位)
//2, SCL------->18 Pin.(当然你可以任意选择脚位)
//3, PORTB----->数码管的段输出
//4, RD4,RD5,RC6,RC7------->数码管的位输出(数码管为共阴极)

鉴于MCS
鉴于MCS-51系统只提供“二级中断嵌套”,提出扩展51系统中断优先级的纯软件方法。其利用51系统内建的中断允许寄存器IE和中断优先级寄存器IP,通过屏蔽字机制来实现;以C51的形式,给出这种扩展方法的函数库实现,为该方法的使用赋予友好、简洁的用户接口。-Given MCS-51 systems only provide "two interrupt nesting," expanded 51 priority system interruption of pure software. The use of 51 built-in system allows interruption Register IE and priority interrupt register IP, through word shielding mechanisms to achieve; C51 in the form of this expansion is the way to achieve functions, methods for the use of empowerment friendly, simple user interface.
