sbit是c51用的
在xc8当然不会直接用
xc8下需改成bit
如下
unsigned char bdata home;
bit father     = home^0;
bit mother1 = home^1;
bit mother2 = home^2;
.
但编译后出错
错误讯息指示这个宣告不正确

当然
XC8是有宣告方式
如下例子
// Register: PORTA
extern volatile unsigned char PORTA @ 0x005;
#ifndef _LIB_BUILD
asm("PORTA equ 05h");
#endif
// bitfield definitions
typedef union {
struct {
unsigned RA0 :1;
unsigned RA1 :1;
unsigned RA2 :1;
unsigned RA3 :1;
unsigned RA4 :1;
unsigned RA5 :1;
unsigned RA6 :1;
unsigned RA7 :1;
};
} PORTAbits_t;
extern volatile PORTAbits_t PORTAbits @ 0x005;

but
太复杂
所以请教高人
XC8有无较简单的方式宣告
