Select where the source operands are located for the following two LC-3 instructions:
0001 111 010 0 00 011 1010 010 110011110
For source operands located in memory, distinguish the addressing mode used to access that memory.
I think the correct answers are fourth and fifth respectively because for the ADD instruction it's apparent that the source operands are directly from a register. Also, the LDI instruction, the second one given, has the source operands from memory using indirect addressing mode. Am I correct in understanding this?
