1. Loading and Storing Data

Load two unique 8-bit values of your choice (specify them as HEX) into two registers (R0 and R1) and two unique 16-bit values of your choice (specify them as HEX) into two other registers (R2 and R3). HINT: use the load and store instructions to do this (e.g., load a value into a register use LDRB and LDR, and store from a register to a memory location using STRB and STR).

2. Understanding the CCR

Write code that will: 1) load register r0 with 0xFFFFFFFF and, 2) add 1 to r0 store the result back into r0. In your report, after execution indicate what is in register r0 and what relevant flags (i.e., N, Z, V, and/or C) are set in the PSR after execution?

3. Instruction Execution Cycle

Please use the commands LDR and STR to load and store a value of your choice. Then show in your screenshots the object code of these instructions. Finally, execute and show the relevant registers and memory locations in your screenshots. In your report, indicate how many cycles were needed to execute each instruction (i.e., this load will take an x amount of cycles, and this store will take a y amount of cycles).
