1 sec delay for 89s52 microconroller

hi, i am using 11.0592MHZ crystal osc, i tried to create delay for exactly one sec (code shown below) but i got only 0.99sec. can anyone help me?

mov r0,#7
l3:mov r1,#255
l2:mov r2,#255
l1:djnz r2,l1
djnz r1,l2
djnz r0,l3
ret

You will only be as precise as one clock instruction...

Using NOP before the ret can fine tune.... How close can you get?
