Consider the following delay subroutine: DELAY MOVLW d 250 MOVWF OXOC LOOP2 MOVLW 0250 MOVWF OXOD LOOP1 (1)NOP (n)NOP DECFSZ oxoDF GOTO LOOP: DECFSZ OxoCF GOTO LOOP2 RETURN END What would be the value of n (how many NOP instructions), if we want to create a delay of 1sec using an oscillator frequency of 4 MHz? P.S. show the details of your work, oliverwise, the answer will not be accepted
