L(28 points) For each of the following questions, assume that the registers are initialized to the following values (i.e., each part is independent of the others). Note: ML is short for memory location. Give the contents of the registers after each instruction is executed. All numbers shown are HEX numbers except when noted otherwise. DO NOT leave any box empty (even if the contents don't change) - empty boxes will be counted wrong! Also, do not use a DASH"_" in a box and do not forget the $-sign for hex numbers. A.
