Method of parameterising an integrated circuit with supply voltage, reference potential and output connectors; parameterising signal is formed by code with edge change after each bit

摘要

The method involves applying a digital start command signal with subsequent parameter data to the supply voltage connector (12) and/or output connector (16). During the paramaterising process a voltage greater than the normal IC operating voltage level exists permanently at the supply voltage connector and/or output connector, which is detected by a detector in the IC (10). The parameterising signal is formed by a code with an edge change after each bit. An Independent claim is also included for an integrated circuit for implementing the method.
