users. When the instruction MCR is executed, the previous state of the switch contact is popped from the top of the stack. Under the conditions listed in (b), (d), and (e) above, the number of times the items are pushed onto the stack may be different from the number of times the items are popped from the stack. When this situation occurs, at most 32 items can be pushed onto the stack, and the items can be popped form the stack until the stack is empty. Therefore, when CJ or CJP is used with MC and MCR, users have to be careful of the pushing of the item onto the stack and the popping of the item from the stack.
