ABSTRACT:
A switching control circuit includes a serial-to-parallel converter, a rewritable storage device, and a decoder. The serial-to-parallel converter performs serial-to-parallel conversion for converting an inputted first control signal into a first parallel signal, and outputs the first parallel signal. The rewritable storage device has a write mode and a read mode selectively switched over in response to a storage mode switching signal, stores therein data of the first parallel signal in the write mode, and outputs the stored data as a second parallel signal in the read mode. In the read mode, the decoder decodes the first control signal and the second parallel signal to generate and output a plurality of element control signals to a plurality of elements, respectively. In the write mode, the decoder holds the plurality of element control signals generated in the read mode.
