I need the formula...............for calculating the value of TH0 in 8 bit auto reload mode only..This is my requirement...
Please help
The formula is "No Can Do".
The maximum interval that can be generated with an 8-bit counter is
256mS. You want 1000mS. 1000 is bigger than 265. Sorry.If only you had bothered to read what Martin posted instead of whining...
hehe
I knew that, the OP didn't even say what his/her Frequency of the xtal was, but on the other hand, s/he asked for the formula, which I didn't know offhand , so I just looked at the source code, of my first html suggestion, and it's more or less there in java coffee stuff code (which I never got the hang of, cos it's on a PC, too big for an embedded mind).
cheers

Not quite.
You CAN generate 1 sec interrupts, from 8 bit reload mode timers, [ given certain conditions ;) ]
We have a product that does exactly this, using AT89LP4052

Did you mean 256uS instead ?
Is there a prescaler in 8051?
