bdata如何运用？ [复制链接]

uchar bdata LedState = 0xFF;            
sbit  LedAh = LedState^0;              
sbit  LedAl = LedState^1;  

sbit  LedK  = LedState^2;     
sbit  LedM  = LedState^3; 

uchar bdata KeySign;                                
                      
sbit  FirstPress  = KeySign^4;                       
sbit  AffirmPress = KeySign^5;                 
sbit  TimeOut     = KeySign^6;     

我想问问:uchar bdata KeySign是不是也等于0xFF;

存储的地址是不是在sbit LedM=LedState^3的后面．
