2. A controller, outputting a control signal which is masked, the controller comprising:
a mask control circuit including:
a second input port receiving a signal also supplied to a monitoring target terminal to be monitored;
a first input port receiving a signal representing a voltage level of the monitoring target terminal; and
an output port outputting the control signal indicating a determination result of whether the voltage level of the monitoring target terminal is in transition based on signals received by the second input port and the first input port; and
a state transition control circuit including an input port connected to the output port of the mask control circuit and an output port outputting the control signal and which switches to one of a plurality of states,
wherein the state transition control circuit is configured to output the control signal which is masked during a period in which the voltage level of the monitoring target terminal is transitioning based on the signal indicating the determination result of whether the voltage level of the monitoring target terminal is in transition.
