(c) The program includes a loop. Which register is being used as a loop counter and how many times in total will the set of instructions within the loop be executed? (d) What is the function of the program? Do not give a description on an instruction by instruction level; give the overall task of the program. (e) Explain the purpose of the instruction LSR #2, D0. (f) Write a program to add two numbers stored at locations $2000 and $2001, and store the sum at location $2002. Test the functionality of the program with test data 3 and 4.
