MPP
Function
1) MPS Stores signal states of this point, waiting to be used when other lines
are output.
2) MRD reads signal from last storage point, connects to the next node, of
which signal status is always the same.
3） MPP brings up signal status from this storage point, connects to the next
node, and removes the status of this node.
4） Every MPS must ends with MPP.
5） The last connection line must be ended with MPP.
