PROBLEM TO BE SOLVED: To efficiently use internal resources of an integrated circuit in regard to a device controller, with a restrained use amount of the flip-flop circuits (FF) in the integrated circuit. SOLUTION: To an access request from a central processing unit (CPU) 1-1, the internal portion of the integrated circuit of a device controller 1-2 receives the access request from the central processing unit (CPU) 1-1 via a CPU interface 1-21, generates and outputs a control signal which successively changes in time series in a sequencer 1-22 using a block RAM. Then, by outputting the control signal to a device 1-3 of control object, the device 1-3 of control object is controlled. Each data stored in the block RAM is successively output on a clock-by-clock basis, as sequence waveform data DOUT[0]-DOUT[n]. Each sequence waveform data DOUT[0]-DOUT[n] is input to the device 1-3 of control object as control signal. COPYRIGHT: (C)2005,JPO&NCIPI
