Extracted text: (b) Consider a 16-bit processor in which the following appears in main memory, starting at location 200: 200 Load to AC Mode 201 500 202 Next instruction The first part of the first word indicates that this instruction loads a value into an accumulator. 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 and the operand to be loaded for the following address modes, also explain the working in cach mode: a. Direct d. PC relative g. Register indirect | c. Indirect f. Register b. Immediate e. Displacement
