I'm trying to find answer of this question.

I tested in Emu8086, when I use MOV, ADD, SUB, MUL,... instructions, the next value of IP increase by 2, but when I use CWD instruction, IP's value increase by 1.

So in this question, I don't know how it actually work.

The value in CS is 1FD0h
What is the location of next instruction from 00000h if Instruction pointer is 3CD4h

Is it 1FD0-3CD5 or 1FD0-3CD6?
