Assume that AL BL = - 30D (2's complement). Execute the following: 1- Write a code to sum the contents of AL with BL and save the result in AL. What is the value of AL and CF? 2- Is the result (signed) correct or incorrect? Why 3- Write an instruction that adds 1 to the contents of the AL register? What is the new value of AL?
