Assuming a Pep/7 machine, what are the contents of the A register after the execution of this instruction:

00001001 00000000 00000010

given the following state of memory (in hexadecimal)?

0001 A2
0002 00
0003 11

00001 is the opcode for the instruction "Load operand into a register (either A or X)"
I know that 01 int the Addressing mode specifier means Direct-mode addressing but after that I'm not sure what to do. I think the answer is 00000000 00010001
