摘要
MCS-51系列单片机有111条指令。这些指令除了常规用法外,许多文献还介绍了不少变通的用法,通过对MCS-51系列单片机指令的变通用法进行归纳。发现有些变通用法的论述,在现有的文献中并不够严谨,因此从理论上完善,同时研究和使用这些变通用法,对拓宽编程思路和提高编程技巧是有积极意义的。
The micro controller unit (MCU) of MCS-51 series has 111 instructions in all. In addition to the regular usages of these instructions, a variety of flexible usages has been introduced in lots of literature. This paper firstly summarizes those flexible usages of the instructions in MCS-51 in general. It also makes a theoretical perfection on them, which are often dissertated not precisely enough in existing literature. Studying on and applying these flexible usages has a positive impact on widening programming ideas and improving programming skills.
