PURPOSE:To attain high-speed processing and to improve cost performance by providing a sequencer to a controller which contains an MPU. CONSTITUTION:When a request is fed from outside for a control action, an MPU1 writes the control information corresponding to said request to a control register 6-1, for example, among those control registers 6-1-6-n via a decoder 5 connected to an address bus 12. At the same time, the data information is written to a data register 11-1, for example, among those data registers 11-1-11-m via a data bus 13. Then the control of a device to be controlled is totally left to a sequencer consisting of a control ROM7 and control signal producing parts 9-1-9-k. The information on production of the control signal which is read out of the ROM7 is converted into the control signals through the parts 9-1-9-k and supplied to devices 23-1, 23-2... to be controlled. Then the answer signals are decided at an answer signal deciding part 14. |
