CCSV5中，unsigned long int ;unsigned short int;unsigned int;还有带符号型变量，它们的长度是几位啊。
如果我定义了一个长整型变量，最后的值为400,000,000，会不会溢出啊
ZhaoF，
建议参考文档“MSP430 Optimizing C/C++ Compiler v 4.1 User's Guide” 链接为：http://www.ti.com/lit/ug/slau132g/slau132g.pdf
的P67， Table 5-1. MSP430 C/C++ COFF ABI Data Types 和 Table 5-2. MSP430 C/C++ EABI Data Types
其中有各种变量在ABI，EABI下的长度。
希望对你有帮助！O(∩_∩)O~
