When using the force limiting with the external force limit and analog voltage reference, make sure that there are no other
signals allocated to the same terminals as /P-CL and /N-CL. When multiple signals are allocated to the same terminal, the
signals are handled with OR logic, which affects the ON/OFF state of the other signals. Refer to
8.3.2 Input Circuit Signal
