PURPOSE:To shorten the test time of a device using a microprogram controller. CONSTITUTION:The microprogram controller is provided with a microprocessor 2 which reads the turning-on/off state of a DIP switch 1 which designates the function to be given to the controller in accordance with the turning-on/off state, a data register means 3 which latches artificial DIP switch data 6 from the microprocessor 2 by a latch signal 7 from the microprocessor 2, a select register means 4 which latches a select signal 8 from the microprocessor 2 by a latch signal 7 from the microprocessor 2, and a selector means 5 which is provided between the DIP switch 1 and the microprocessor 2 and selects output data of the data register means 3 or data read from the DIP switch 1 by the output of the select register means 4. |
