3. Program example 3 (Two stacks)
4. Program example 4 (Four stacks)
In programming a circuit on the upper side, it is necessary to use MPS instruction three times.
By changing the circuit on the upper side into the circuit on the lower side, the same contents can be
programmed easily without MPS instruction.
