I have gone through the tutorial but still the question is not answered:-

if some one asks you whats the difference between a Counter and Timer , what is your answer not the tutorial one?

Next please check if iam on the right track about writing program for 1 second delay:-

Using 12 Mhz crystal.

12/12 = 1000000 timer will increment in a second.

so we need to increment the timer 1000000 times in a second to get a 1 second delay.

But since the 16 bit timer will over flow after 256*256=65536 finding other value:-

For this lets say i have selected a rounded value 50000, Now i will multipy this by some number in order know how many times the counter should count 0-50000 to get a value of 1000000.

so 50,000 x 20 = 1000000

so my code should be such that timer count from 0-50000 20 times.

now for values of TH0 and TL0:-

doing the following subraction
65536
-50000
-------
15536 decimal

now converting the above into HEX

MOVing the left hand 2 digits in THO and moving right hand side 2 digits in TLO

Is it ok...

But if it is, then writing a code for 1 Minute requires NESTED LOOPS coz it will require 50000 x 20 x60 times counter should runs...

is there any easier way out...
