Here is a basic method to send data via UART.
My question is probably simple but I'm just asking
that if I can control the time of while(!TI)
on the following code. I don't know which things
give a time of that and I need to make it as
shorter as possible. Any methods for this control
or comments are helpful. Thank you very much.

while(!TI);
TI = 0;
SBUF = date;
