<p>PURPOSE:To process the plural systems of data signals by the same program by providing a switching means to connect an output from any one of plural input ports to one input register selectively corresponding to a control signal. CONSTITUTION:A switching means 10 is provided to connect the output from any one of plural input ports IN1 and IN2 to one input register 6 selectively corresponding to the control signal. Therefore, the same processing as an arithmetic processing executed to the digital signals supplied to the first input port IN1 can be executed to the digital signal to be supplied to the second input port IN2 as well without changing the program written to the inside. Thus, since the number of programs to be stored in a memory in a microcomputer can be decreased, the memory having large memory capacity is not required and cost can be reduced.</p> |
