请教CCS中#pragma怎么用 [复制链接]

我用CCS5.4 按照https://bbs.eeworld.com.cn/forum ... ight=MSP430%2BFLASH

里边的方法想操作FLASH,但是出现这个警告



这个怎么弄？是得包含什么头文件吗？

C/C++ compiler supports the following pragmas:
• CHECK_MISRA (See Section 6.10.1)
• CLINK (See Section 6.10.2)
• CODE_ALIGN (See Section 6.10.3)
• CODE_SECTION (See Section 6.10.4)
• DATA_SECTION (See Section 6.10.5)
• DIAG_SUPPRESS, DIAG_REMARK, DIAG_WARNING, DIAG_ERROR, and DIAG_DEFAULT (See
Section 6.10.6)
• FAST_FUNC_CALL (See Section 6.10.7)
• FUNC_EXT_CALLED (See Section 6.10.8)
• FUNCTION_OPTIONS (See Section 6.10.9)
• INTERRUPT (See Section 6.10.10)
• MUST_ITERATE (See Section 6.10.11)
• NO_HOOKS (See Section 6.10.12)
• RESET_MISRA (See Section 6.10.13)
• RETAIN (See Section 6.10.14)
• SET_CODE_SECTION (See Section 6.10.15)
