Suppose we have the instruction Load 1000. given memory and register R1 contain the
values below:
Memory
0x1000 0x1400
R1
0x200
0x1100
0x400
0x1200 0x1000
0x1300
0x1100
0x1400 0x1300
and assuming R1 is implied in the indexed addressing mode, determine the actual value loaded
into the accumulator and fill in the table below:
Mode

Direct
Indirect
Indexed
Value Loaded
into AC
