Problem 1 Consider the piece of ARM Cortex MO+ assembly code given below and answer the following questions: mw 1.AGAIN CMP RO, #10 BLE LESSEQUAL MOVS RO, #0 B DONE LESSEQUAL ADDS RO, RO, R1 B AGAIN 5. DONE 1. Assume RO is initialized with the value 20, what is the value of RO when the code above completes execution? How many times is Instruction 5 executed? Assume RO is initialized with the value o, and R1 with the value 1, how many times is Instruction 4 executed? 3. Assume now that RO is initialized with the value 0 and R1 with the value 2, how many times is instruction 4 executed? 4. What happens when RO is a decimal digit between 0 and 9 but R1 is initialized with the zero value? 5. What instructions would you add and where to prevent the above code from entering into an infinite loop
