Integrated circuit device including a spectrum spread clock generator, method for controlling the device, and ink-jet recording apparatus including the device
An integrated circuit device is provided including a plurality of circuit blocks which operate based on a clock signal. The quartz oscillation circuit outputs a first clock signal. A spectrum spread clock generator outputs a second clock signal having a spread frequency. A clock signal is output to the plurality of circuit blocks and, based on an instruction to output the clock signal from a CPU, a clock signal output to the plurality of circuit blocks is switched from the second clock signal to the first clock signal.
