Abstract
PURPOSE: To display a lot of input data on many indicators at a high speed, by a controller using a microprocessor.
CONSTITUTION: To an output circuit 23 having the first area for writing data to be displayed, and the second area for writing a signal for instructing a display part to store the data, the display part 25 is connected through a data bus. In this state, it is instructed by a CPU22 to output the data of the first area to the data bus to the output circuit 23, and also a signal of the second area is sent out to the display part 25 for displaying the data. Accordingly, an input data D is inputted from a circuit 21, is processed by the CPU22 in accordance with program logic stored in an ROM26 and also by use of rewritable data stored in accordance with processing, in an RAM27, and after that, is outputted to a bus 24 from the output circuit 23, and is displayed on the indicator 25.
