Relative Addressing Mode

Question

Answer 1

In Relative Addressing Mode EA is calculated=Operand Address+PC value

PC points to next instruction.

Here it is 2 word instruction

Address of word=W

So, next instruction to be executed in W+2

Adress field of instruction Y is M[Y]

So, relative address will be =(W+2)+M[Y]

Comments

Given ans D..

Is there any possibility for option A??

---

yes. because y=w+1 so  y+1=w+2,    at y+1 we have starting of another address field that will be the PC value.

---

Shouldn't the question say:"The address of the address field of the instruction is designated by Y"?

Because in that case only w+2=y+1 is satisfied.
