How to Read and Write Individual Bits

#define BitVal(data,y) ( (data>>y) & 1)             // Return Data.Y value
#define SetBit(data,y)    data |= (1 << y)          // Set Data.Y to 1
#define ClearBit(data,y)  data &= ~(1 << y)         // Clear Data.Y to 0
#define TogleBit(data,y)     (data ^=BitVal(y))     // Toggle Data.Y value
#define Togle(data)   (data =~data )                // Toggle Data value
