hi rupak,
Timer set in mode1 means 16 bit mode.
keep timer count tl0,th0 with ur maximum values...
otherwise do onething keep th0=30,
tl0=00 and run this timer 10 times..
means upto 10 times be in loop.
after that only u access timer interrupt...
dont forget to reload count...
my th0=30,tl0=00 approximately gives 1 sec
delay.for ur 10 sec delay change count.
hope it will works for u..
