Consider the $8051$ assembly code.

org $000$ h

mov it$,$#$45$h

mov $2,$#$40$ n

mov ro$,$ #OCh

Lt mov a$.$ @n

mov ari $2,$a

inc $n$

inc $12$

djnz r$0,$L$1$

end

The program transfers $12$ bytes of data from location $45h$ to $40h$

The program transfers $10$ bytes of data from location $40h$ to $45h$
