Abstract:
1. A control circuit in which an analog switch is built, an ON/OFF timing of the analog switch can be controlled, a plurality of mask patterns can be set, one of the mask patterns which is used for switching ON/OFF the analog switch can be selected by analog switch selection data, and a number of the mask patterns which can be set can be selected, the control circuit comprising: a plurality of mask pattern setting units configured to set one of the mask patterns by one of switching control signals; and a selection unit configured to select a mode from a plurality of modes including a first mode in which the number of mask patterns is smaller and a second mode in which the number of mask patterns is larger, wherein, when the first mode is selected by the selection unit, to one of the mask pattern setting units which is not selected by the analog switch selection data, the same one of the switching control signals that is supplied to another one of the mask pattern setting units which is selected by the analog switch selection data is supplied.
