Yes!
The interrupt can hit at any time - the interrupt is sampled at the instruction fetch time - so it can happen between any instruction. In your case it could happen on line #1,2 or 3, so yes, there could be an instance where the memory location 30h has a value of 0 when the interrupt hits before the jmp start or mov 30h,#40h instructions. |
