摘要
Keil公司推出的C51编译器事实上是80C51 C编程的工业标准,在Keil C编程环境下8051系列单片机寄存器组的使用具有一定的规律,特别是中断程序中寄存器组的使用需特别注意。文章通过对中断程序中寄存器组的保护机理进行分析,总结出适合KeilμVision V7.50环境下中断函数编程时需注意的事项。
The Atmel＇s singlechip 80C32E is largely used in Space servo controller owning high reliability and long life.In fact,the Keil＇s C51 compiler is already the industry standard for 80C51 programming.There are some laws for using register group of 8051 series MCU-especially the interrupt register group.Base on the analysis of protection mechanism of interrupt register group,this article summarizes the notice proceedings in Keil μVision V7.50 programming environment.
