：为了发挥 C 语言和汇编语言各自的优点，二者需要相互调用函数。本文首先介绍了

MSP430 单片机的 C 语言函数的参数传递规则，然后对 C 语言和汇编语言的混合编程进行

了详细描述，最后给出应用实例。-: In order to play a C and assembly language with their respective advantages, the two need each function is called. This paper describes the MSP430 microcontroller C-language function parameter passing rules, and then C and assembly language programming mix is described in detail, and finally gives a practical example.
