I did the math for it but I'm very confused on how to actually fill out the question

13.4 Consider a 16-bit processor in which the following appears in main memory, starting at location 200: 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: a. Direct b. Immediate c. Indirect d. PC relative e. Displacement f. Register g. Register indirect h. Autoindexing with increment, using R1 Solve problem 11.4. (Parts a, b, c and h only) a) address: operand: b) address: operand: c) address operand: h) address: operand
