使用带有IAR的STM8L101F3没有库函数访问

我正在使用带有IAR的STM8L101F3。我想设置并清除激活级别位。

没有库函数来访问它，我不知道如何从代码访问该寄存器。

查看iostm8l101f3.h，定义了寄存器和位：

/ *全局配置寄存器* /
#ifdef __IAR_SYSTEMS_ICC__
typedef结构
{
unsigned char SWD：1;
unsigned char AL：1;
} __BITS_CPU_CFG_GCR;
＃万一
__IO_REG8_BIT（CPU_CFG_GCR，0x7F60，__ READ_WRITE，__BITS_CPU_CFG_GCR）;

#define CPU_CFG_GCR_AL CPU_CFG_GCR_bit.AL

但是尝试使用以下代码修改代码中的位：

CPU_CFG_GCR_AL = 1;

生成错误：错误[Pe020]：标识符''CPU_CFG_GCR_AL''未定义

我该怎么修改这个位？



以下为原文




I'm using the STM8L101F3 with IAR. I would like to set and clear the Activation level bit.

There is no library function to access this and I'm not sure how to access this register from code.

Looking at iostm8l101f3.h, the register and bit is defined:

/* Global configuration register */
#ifdef __IAR_SYSTEMS_ICC__
typedef struct
{
   unsigned char SWD         : 1;
   unsigned char AL          : 1;
} __BITS_CPU_CFG_GCR;
#endif
__IO_REG8_BIT(CPU_CFG_GCR, 0x7F60, __READ_WRITE, __BITS_CPU_CFG_GCR);

#define CPU_CFG_GCR_AL           CPU_CFG_GCR_bit.AL

But trying to modify the bit from code using:

CPU_CFG_GCR_AL = 1;

generates an error:  Error[Pe020]: identifier ''CPU_CFG_GCR_AL'' is undefined

How can I modify this bit?
