IAR编译问题

这些都能在430的头文件里找到。

__intrinsic void __no_operation(void);

__intrinsic void __ena××e_interrupt(void);

__intrinsic void __disa××e_interrupt(void);

__intrinsic istate_t __get_interrupt_state(void);

__intrinsic void __set_interrupt_state(istate_t);

__intrinsic void __op_code(unsigned short);

__intrinsic unsigned short __swap_bytes(unsigned short);

__intrinsic void __bic_SR_register(unsigned short);

__intrinsic void __bis_SR_register(unsigned short);

__intrinsic unsigned short __get_SR_register(void);

__intrinsic void __bic_SR_register_on_exit(unsigned short);

__intrinsic void __bis_SR_register_on_exit(unsigned short);

__intrinsic unsigned short __get_SR_register_on_exit(void);

还有

__intrinsic unsigned short _BIS_SR(unsigned short);

__intrinsic unsigned short _BIC_SR(unsigned short);

__intrinsic unsigned short _BIS_SR_IRQ(unsigned short);

__intrinsic unsigned short _BIC_SR_IRQ(unsigned short);

__intrinsic unsigned short _BIS_NMI_IE1(unsigned short);

还有

#define _DINT() __disa××e_interrupt()

#define _EINT() __ena××e_interrupt()

#define _NOP() __no_operation()

#define _OPC(x) __op_code(x)

#define _SWAP_BYTES(x) __swap_bytes(x)

类似的

Peter，您好！我的io430.h文件里怎么没有这些函数啊...你这应该是在CCS下的头文件里吧..

您好！CCS下做了重新的宏定义
