Dear sir,

I have studied that when micro controller transmits data successfully it makes TI flag to 1. I am checking the output of serial communication by using the keil software.The timer interrupt flag(TI) is not setting automatically , I had to set manually every time.Is that code works when I dump in to my micro controller ?. Is the micro controller sets the TI flag to one automatically ? Please help me



SBUFF='W';
while(TI==0); // It is not coming out of this loop I had to set make TI=1 manually
TI=0;
