Configuring the operational behavior of an integrated circuit. The integrated circuit (IC) comprises a plurality of configuration inputs for configuring the IC. The IC also has a memory which stores a plurality of sets of parameter values. Each parameter value of the respective set corresponds to a different operational parameter of a plurality of operational parameters. The IC includes logic which determines a first plurality of configuration values corresponding to the first plurality of configuration inputs. The logic then selects a set of parameter values from the stored plurality of sets of parameter values. The selection of parameter values is based on the first plurality of configuration values. The IC is then configured for operation according to one or more operational parameter values in the selected set of parameter values.
