Part 1 of 4 - Let's create a straightforward example. MOV r1, #2; Put 2 in register rl MOV r2, #-3; Put -3 in register r2 ADD r0,ri, r2;Add rl to r2 and put the result in ro Note how simple the instructions are. Basically, each instruction performs one primitive operation. Note also, the semicolon indicates the start of a comment field that is not part of the executable code. Use the Keil simulator to write, assemble, and run the above program fragment. Do you get the expected answer, especially the negative numbers? Note that you will need to use appropriate assembly directives to make this program fragment a program. Modify your program by initializing the values of r1 and r2 using literals, as shown below. Assemble and run the 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 1 of 4 4.0 Points When the value of r1 is -4, and the value of r2 is -2, the value of ro in 8 hexadecimal digits will be 0x Mark for Review What's This?
