Case
 When SSP_Ex changes from FALSE to TRUE, DMC_SetStartPosition instruction is executed.
In the same cycle, SSP_Bsy changes from FALSE to TRUE. In the second cycle, SSP_Done
changes from FALSE to TRUE and meanwhile SSP_Bsy changes from TRUE to FALSE. So the
start positions of axes in G codes for the motion is the start positions set by the instruction.
 When SSP_Ex changes from TRUE to FALSE, SSP_Done changes from TRUE to FALSE.
