Assuming the clock frequency of the PIC18 microcontroller is 4MHz, determine the time delay generated by the following code fragment in microseconds (us). DO NOT Include the first four instructions in your calculation. Count the looping part only.

Main: movlw d'20' movwf DELAY_L, A movlw d'3' movwf DELAY_H, A DelayLoop: decfsz DELAY_L, F, A goto DelayLoop decfsz DELAY_H, F, A bra DelayLoop Answer (in microseconds)
