GATE EC 2002 Set 1 Q2.13 — Computer Organization

Consider the following assembly language program.

$\begin{array}{rll} \text{ MVI } & \text{ B,87H } \\ \text{ MOV } & \text{ A, B } \\ \text{ START : JMP } & \text{ NEXT } \\ \text{ MVI } & \text{ B, OOH } \\ \text{ XRA } & \text{ B } \\ \text{ OUT } & \text{PORT1} \\ \text{HLT} & \\ \text{ NEXT : XRA} & \text{B} \\ \text{ JP } & \text{START} \\ \text{OUT} & \text{PORT2} \\ \text{HLT} & \end{array}$

The execution of the above program in an 8085 microprocessor will result in
