Problem 2. Suppose that the following instructions are found at memory locations 01 and 02. Suppose that the following data are found at memory 15 and 16. Addresses 01-02 represent the program area Addresses 15-16 represent the data area Show the contents of the PC, MAR, MDR, IR, and A registers as each step of the fetch-execute cycle is performed for instructions at addresses 01 and 02 . Note that you have a sequence of two instructions. The 5 steps in the second instruction SUB 16 will gradually replace the contents of the registers set by the first instruction. The machine cycle for the LDA instruction that is in the lecture notes for Chapter 7 and that we discussed on Panopto and/or MS Teams would be helpful. Instruction: 01 LDA 15 Instruction: 02 SUB 16
