Example:
1. Before the instruction DPIDE is executed, the setting of the parameters should be complete.
2. When X0.0 is ON, the instruction is executed. When M1 is ON, the DPIDE algorithm is
implemented. When M1 is OFF, the MV is 0, and the MV is stored in D200. When X0.0 is
switched OFF, the instruction is not executed, and the previous data is unchanged.
