SS stores the address of the bottom of the stack SP contains the address of the top of the stack Here SP stores (7890)16 ..therefore the address of the top of the stack is 7890 If ABCD is to be stored then CD will be stored at address 7891                                            AB will be stored at address 7892 Now SP will have address 7892 (since it is the new top of the stacknow)
