hi,


i think there is deep confusion about the working of the timers. Mr. Karas makes it clear in his post.

more, the interrupt are used where PU has somthing to do, while waitng for some condition. if PU is poling the flag set by interrupt driven by the timer no point in making it interrupt driven, instead, TF0 itself can be polled to creat delay. please clearify, what is that delay used for?.
