CCS报错 error: expected an expression如何解决？

我按照参考书上的示例程序编写自己的初始化程序：void init_board(void)
{

*(volatile unsigned int *)CLKMD=0x0000;

while(*(volatile unsigned int *)CLKMD & 0x0001){};

*(volatile unsigned int *)CLKMD=CLKMD_VAL;

*(volatile unsigned int *)PMST=PMST_VAL;

*(volatile unsigned int *)SWWSR=SWWSR_VAL;

*(volatile unsigned int *)SWCR=SWCR_VAL;

*(volatile unsigned int *)BSCR=BSCR_VAL;

*(volatile unsigned int *)ST1=ST1_VAL;
//设置CPU寄存器

*(volatile unsigned int *)SPSA0=SPCR10;
//以下初始化MCBSP0

*(volatile unsigned int *)SPSD0=SPCR10_VAL;

*(volatile unsigned int *)SPSA0=SPCR20;

*(volatile unsigned int *)SPSD0=SPCR20_VAL;

*(volatile unsigned int *)SPSA0=RCR10;

*(volatile unsigned int *)SPSD0=RCR10_VAL;

*(volatile unsigned int *)SPSA0=RCR20;

*(volatile unsigned int *)SPSD0=RCR20_VAL;

*(volatile unsigned int *)SPSA0=XCR10;

*(volatile unsigned int *)SPSD0=XCR10_VAL;

*(volatile unsigned int *)SPSA0=XCR20;

*(volatile unsigned int *)SPSD0=XCR20_VAL;

*(volatile unsigned int *)SPSA0=SRGR10;

*(volatile unsigned int *)SPSD0=SRGR10_VAL;

*(volatile unsigned int *)SPSA0=SRGR20;

*(volatile unsigned int *)SPSD0=SRGR20_VAL;

*(volatile unsigned int *)SPSA0=PCR0;

*(volatile unsigned int *)SPSD0=PCR0_VAL;

}

结果每一行都报错：
"initialize.h", line 5: error: expected an expression
"initialize.h", line 6: error: expected a ")"
"initialize.h", line 7: error: expected an expression
"initialize.h", line 8: error: expected an expression

"initialize.h", line 10: error: expected an expression

"initialize.h", line 29: error: expected an expression
"initialize.h", line 30: error: expected an expression
26 errors detected in the compilation of "control.c".

寄存器名是在另一个头文件中定义的，如：
#define ST1 0x0007;//Status register 0
#define ST0 0x0006;//Status register 1
#define PMST 0x001d;//Processor mode status (PMST) register
#define SWWSR 0x0028;//Software Wait-State Register
#define SWCR 0x002b;//Software Wait-State Control Register
#define BSCR 0x0029;//Bank-Switching Control Register
#define CLKMD 0x0058;//Clock Mode Register (CLKMD)

请高手解答 我用的是CCS 2.21

自己回答：原来是由于我在宏定义后面加了分号，去掉后就正常了
