[5*4 20 Points] Problem 5: Consider a 16-bit processor in which the following appears in main memory, starting at location 200 200 201 202 Load to AC Mode 500 Next instruction The first part of the first word indicates that this instruction loads a values into AC. The Mode field specifies an addressing mode and, if appropriate, indicates a source register; assume that when used, the source register is R1, which has a value of 400. There is also a base register that contains the value 100. The value of 500 in location 201 may be part of the address calculation. Assume that location 399 contains the value 999, location 400 contains the value 1000, and so on. Determine the effective address (EA) and the operand to be located for the following address modes: A. Direct B. PC relative C. Indirect D. Displacement E. Register
