Respected Sir

Thanks a lot for your kind reply. I have tried with his suggestion also but still I was getting value 0. Please explain me in depth. I am doing something wrong which I am not able to understand. Kindly guide me.

I had used this code also

byte WriteByte (byte value) {
  SPDR = value ;
  while (!(SPSR & (1<<SPIF)))
  {}
  return SPDR ;
}
