Address after Halt instruction

Question

Consider that the memory is byte addressable with size 16 bits, and the program has been loaded starting from memory location (2000)₁₀. What will be the return address saved in the stack, if an interrupt occurs while the CPU has been halted after executing the HALT instruction?

I am getting 2018.

There are $2$ point of view of executing HALT statement :
either its infinite looping of same instruction in this case answer is : $2016$
else from programmer point of view execution of halt will execute next address instruction in that case its : $2018$

I also had similiar doubt and posted here : https://gateoverflow.in/188803/gate_questions_doubt

its given that memory is byte addressable, so 1 word = 1 byte. why are have you taken 1 word = 2 bytes ?

---

I think the word size is 16 bits = 2 Bytes. Also, byte addressable does not mean that 1 word = 1 Byte.

According to the gate 2004,2007 question it should be 2018

Answer 1

 CPU has been halted after executing the HALT instruction.

it should be 2018.

why you took word length is 2 byte?

Word size is =16 bits (2 bytes)

---

could u plz tell how the first instruction will take address to 2003?

for 1st instruction , instruction size given as 2 words, here 1 word = 2B(16 bits ) that's why
