I use Keil sometimes and while using a timer in autoload mode, the TH0 is loaded with the calculated value but TL0 starts incrementing from 00 instead of the calculated value F0.Am I missing something while using or configuring the keil simulator?
your code will have the exact same "problem" - if the code didn't return from his "while (TF1==0);", it wouldn't return from your "while (TF1==0);". thus why i called your line of thoughts "secondary".
TR1 = 1; while(TF1==0);/*Polling mode is used instead of interupt mode*/
will continue, a running timer (0 or 1) will (eventually) set TF to 1.

'will continue, a running timer (0 or 1) will (eventually) set TF to 1.'
that's the point of the entire discussion, erik: his code, as well as yours, SHOULD work. but he reported it didn't work.
both of you used exactly the same return mechanism "while (TFn==0);". so if his code, for whatever reason, didn't return from that, your code wouldn't return from that either. using mode 1 vs. 2 does NOT matter at all from that perspective.
jesus! is it really that unreasonable to expect people to have some minimum reading comprehension?
it does work, I have a sneaky suspicion that autoload mode confuses the simulator. Not the first time the simulator has 'simulated' instead of 'replicated'. If it confuses the chip the chip is defective.
why on earth not just see what happens with non-autoload the OP has it right at his fingertips and trying it instead relying on bile from the homewrecker would take, at most 5 minutes.
