Refer to the assembly language program shown in Figure Q4, determine the status of the carry flag, sign flag, overflow flag, zero flag and the value stored in the BX register when the program is executing the statement JMP $. What is the task achieved by the program? Explain how you can utilize the ADC (add with carry) instruction to achieve the same task as that given in program of Figure Q4. Note: the LOOP instruction will not change the flag status.
