Abstract
According to one embodiment, a control circuit for an inkjet head or the like includes an input circuit configured to receive drive information for driving liquid ejection from a plurality of nozzle arrays. The drive information includes a drive signal value to be supplied to a channel of the plurality of nozzle arrays. A latch circuit array of the control circuit has latch circuits for storing the drive information for each array in the plurality of nozzle arrays. A setting register is configured to receive a setting value to configure the input circuit to correspond to a connection mode for the plurality of latch circuits. The setting value corresponds to the number of arrays in the plurality of nozzle arrays.
