I1: 3000 - 3007 // since it is a memory transfer op.
I2: 3008 - 3011// it is an ALU oper.
I3: 3012 - 3015 // it is also an ALU por.
I4: 3016 - 3023 // memory transfer opr.
I5: 3024 - 3027 // ALU oper.
I6: 3028 - 3029 // branch operation
I7: 3030-3033 // ALU Opr.
Halt is an un-conditional branch to the same instruction, i.e, It is a branch instruction.
further more irrespective of whether interrupt occurs during execution of instruction or after execution of instruction next address instruction will be saved to the stack:
So 3030 will be stored in the stack.
