Function
DMC_ReadMFunction is used for reading the state of M code and the data from it. When the G code
execution reaches where the M code set by the instruction is, MFunction changes to TRUE and
meanwhile MFunctionValue outputs the parameter value after M code. The firmware of V1.01 and
above supports the function.
