<p>A semiconductor integrated circuit that executes processing in accordance with a preset program and that allows alteration of product specification settings such as the provision or lack of a pull-up resistance at an input/output terminal, the attributes of terminals, peripheral circuit functions, and communication protocol, even after these product specifications have been set once. This semiconductor integrated circuit is provided with a nonvolatile memory that includes a rewritable program region for storing programs to be executed, a programmable product specification setting region for storing product specification setting information that controls product specifications, and a selector for selecting and putting into operation the program region and product specification setting region. When the product specification setting region is selected, product specification setting information is outputted from the nonvolatile memory directly as product specification selecting signals. <IMAGE></p> |
