Hi to all engineers.

I need to know the function of nop in this sourse code.
I know nop means no operation and  saves one cycle
but still I do not imagine the purpose of nop in this code.

port_setup
        movlw   h'3e'
        movwf   gpio
        nop             ; what does nop do in this line?
        movlw   h'3e'
        tris    gpio

Andre                           thank you
