CONFIGURATION CONTROLLER FOR AND A METHOD OF CONTROLLING A CONFIGURATION OF A CIRCUITRY

摘要

A configuration controller for and a method of controlling a configuration of a circuitry are provided. The configuration controller comprises an input, a selection checker, a data selector and an output. The input receives an input configuration selection signal which is encoded according to a specific encoding scheme. The selection checker checks a correctness of the received input configuration selection signal and provides to the data selector a selection signal which indicates a specific configuration selection if the input configuration selection data is correct or indicates a default configuration selection if the input configuration selection signal is incorrect according to the specific encoding scheme. The data selector selects configuration data from its internal configuration data storage in accordance with the selection signal and provides the selected configuration data to the output.
