Zcmop defines eight 16-bit MOP instructions named C.MOP.n, where n is an odd integer between 1 and 15, inclusive. C.MOP.n is encoded in the reserved encoding space corresponding to C.LUI xn, 0. Unlike the MOPs defined in the Zimop extension, the C.MOP.n instructions are defined to not write any register. In current implementation, C.MOP.n only has an check function, without any other more behavior.
