Abstract: A rotary element is equipped with a pattern representing a reflected binary code on at least three bits. A detection circuit is configured to sense the pattern and deliver an incident signal encoded in reflected binary code on at least three bits. The incident signal is converted by a transcoding circuit into an intermediate signal encoded in reflected binary code on two bits. A decoding stage decodes the intermediate signal and outputs at least one clock signal representing the amount of rotation of the rotary element and a direction signal representing the direction of rotation. A processing circuit determines the movement of the rotary element, and has at least one general purpose timer designed to receive the at least one clock signal and direction signal.

Abstract: An apparatus having a microcontroller includes a processing unit, an internal communication bus assembly, a volatile memory, a non-volatile memory, a logic error management circuit, and two interface circuits. A first interface circuit couples the processing unit to the volatile memory via the internal communication bus assembly. A second interface circuit couples the processing unit to the non-volatile memory via the internal communication bus assembly. When the microcontroller is operating, the interface circuits are arranged to retrieve and evaluate requested data from their respective memory without intervention from the processing unit. In the event a failure is detected, the logic error management circuit is arranged to assert a stop signal. In some cases, detecting a failure includes comparing a check value stored in memory with a check value calculated from the data retrieved from memory.
