Part 2 of 4 - Write a simple program to perform: Z = A + B-( CD). The instructions you may use are MOV, ADD, SUB, and MUL. First, you need to move the values of A, B, C, and D into registers r1, r2, r3, and r4, respectively. The result (i.e., Z) will be put into ro. Use the Keil simulator to write, assemble, and run the above program. What is the value of ro in 8 hexadecimal digits after running the program? Write each hexadecimal digit in a box, i.e., do not write more than one digit in each box. you have to fill ALL boxes, even if its value is zero. Question 2 of 4 6.0 Points When the values of A, B, C, and D are 7, 1, 6, and 5, respectively, the value of ro in 8 hexadecimal digits will be 0x
