请教傻孩子，关于结构体定义到flash区

86csx

傻孩子大侠，我把你“有谁能够谈谈LCD中菜单的实现和编程方法？”中的结构体定义到flash区中，如下，经iar编译没错，但仿真时发现好像在data区中也定义了，不知这样定义是否正确，仿真时data区中出现flash区中定义结构体的相同内容，是怎么回事，不解，望赐教。谢谢！
void nullsubs(void)
{
}
struct menuitem
{
    uchar menucount;
    uchar *displaystring;
    void (*subs)();
    struct menuitem __flash *childrenmenus;
    struct menuitem __flash *parentmenus;
};

__flash struct menuitem timemenu[4];
__flash struct menuitem voicemenu[5];
__flash struct menuitem robotmenu[5];
__flash struct menuitem mainmenu[3];

__flash struct menuitem timemenu[4]=
{
  {4,"time set",nullsubs,NULL,mainmenu},
  {4,"date set",nullsubs,NULL,mainmenu},
  {4,"alert set",nullsubs,NULL,mainmenu},
  {4,"back",nullsubs,mainmenu,mainmenu}
};
__flash struct menuitem voicemenu[5]=
{
  {5,"voice recode",nullsubs,NULL,mainmenu},
  {5,"play",nullsubs,NULL,mainmenu},
  {5,"stop",nullsubs,NULL,mainmenu},
  {5,"delect",nullsubs,NULL,mainmenu},
  {5,"back",nullsubs,mainmenu,mainmenu}
};
__flash struct menuitem robotmenu[5]=
{
  {5,"turn left",nullsubs,NULL,mainmenu},
  {5,"turn right",nullsubs,NULL,mainmenu},
  {5,"go ahead",nullsubs,NULL,mainmenu},
  {5,"go back",nullsubs,NULL,mainmenu},
  {5,"back",nullsubs,mainmenu,mainmenu}
};
__flash struct menuitem mainmenu[3]=
{
  {3,"time set",nullsubs,timemenu,NULL},
  {3,"voice center",nullsubs,voicemenu,NULL},
  {3,"robot control",nullsubs,robotmenu,NULL}
};

这主要取决于你用什么编译器。并不是说数据放在flash区域里面就表示这些数据不会
在被使用的时候零时的出现在RAM中。IAR的具体处理方式我没有仔细研究过，不敢乱下
结论。

嗯，我再研究一下，谢谢你
