MC is the master-control start instruction. When MC instruction executes, the program execution
turns to the designated nest level and executes the instructions between MC and MCR. However,
MCR is the master-control reset instruction placed at the end of the designated nest level and no
drive contact is required before MCR. When MC/MCR is not active, devices and instructions
between MC/MCR will operate as the following table.
