Assume that AC = 63E1, PC = 5C8, AR = 6EF, M[6EF] = 7800, M[5C8] = A74C, M[74C] = 1B31. Determine what instruction would be fetched next. Direct memory reference to store content of AC to memory Register reference to clear AC Indirect memory reference to load memory word to AC Direct memory reference to branch unconditionally
