Consider a 16-bit processor in which the following appears in main memory, starting at location 200: 7. 200 Load to AC Mode 201 202 Next instruction 500 The first byte of the word indicates that this instruction loads a value into accumulator. The Mode field specifies an addressing mode. The base register for displacement addressing holds 100. The value 500 in location 201 is the second byte of the instruction. Assume memory 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 addressing modes a. Direct b. Immediate c. Indirect d. PC relative e. Displacement
