3. In this problem, we design a digital safe system using a PIC18 microcontroller. The system has a predefined password combination. The size of the password is one byte. The predefined combination is denoted as P=P7..P0. The other combination is entered by the user and denoted by C=C7...CO. The requirements for this project are given as follows: a) The predefined combination is stored in a file register addressed at 0000. This combination is P=0xLM, where L is the month of your birth, M is the first digit in the day of your birth. b) The input combination is entered through port C, and then, stored in a file register addressed at 0x010. c) The output is an LED connected to one of the pins of port B. The LED turns on when the two combinations are equal. (5 pts) How are you going to check whether the password and the user input are the same or not? Describe your idea
