单片机设计中C函数和汇编子程序的相互调用及实例

The call between Function C and assembly sub-program in micro-controller programming

本文讨论如何在FranklinC5 1和A5 1的编程过程中 ,实现C函数和汇编子程序的相互调用。内容涉及C5 1函数及其相关段的命名规则 ,调用中两种参数的传递规则 ,最后 ,给出了一个在汇编中调用C5 1函数的实例。

The present paper discusses a successful call between Function C and the assemble sub-program in the programming process of Franklin C51 and A51 It deals mainly with Function C51, the naming rule in its concerning segments and the transmitting rule in calling the two kinds of parameters An example for calling Function C51 in assembly language is also given in the paper
