    Abstract: A bus microcontroller includes a processor circuit having at least one unit designed for performing one or more functions due to a bus command via a communication bus, a power control circuit adapted to be coupled to a transmitter-receiver circuit for receiving bus messages via the communication bus, and a means for placing at least part of the processor circuit into a reduced-power operating mode without placing the entire processor circuit into the reduced-power operating mode. The power control circuit is designed to evaluate incoming bus messages with respect to an activation bus message containing information on activating at least part of the processor circuit, and to output a corresponding activation control signal. The bus microcontroller also includes means for activating at least a part of the processor circuit that is placed in a reduced-power operating mode, in response to output of an activation control signal of the power control circuit.

    Abstract: In embodiments, a reset management circuit executes reset, configuration, and software runtime phases when a processing system is switched on, where one or more microprocessors start at respective start addresses. During the configuration phase, a circuit reads a boot record from a non-volatile memory and stores it to registers. The circuit sequentially reads data records of configuration data from the non-volatile memory and generates a write request for each data record to store the data of the respective data record to a second circuit with associated address data indicated in the respective data record. The processing system processes the boot record and boot configuration data provided by the second circuits to selectively start a predetermined microprocessor at a default start address or at a start address indicated by the boot configuration data, or start one or more microprocessors at respective start addresses as indicated by the boot record.

    Abstract: A processing system includes a processing core including a microprocessor, a memory controller configured to read software instructions for execution by the processing core, a plurality of safety monitoring circuits configured to generate a plurality of error signals by monitoring operation of the processing core and the memory controller, a fault collection and error management circuit implemented as a hardware circuit, and a connectivity test circuit. The fault collection and error management circuit is configured to receive the plurality of error signals from the plurality of safety monitoring circuits and generate one or more reaction signals as a function of the plurality of error signals. The connectivity test circuit is configured to, during a diagnostic phase executed by the processing system after executing a reset phase and before executing a software runtime phase, test connectivity between the plurality of safety monitoring circuits and the fault collection and error management circuit.

    Abstract: An example processing system includes a processing circuit, a volatile memory and a CAN communication controller circuit. The CAN communication controller circuit includes configuration and status registers. A transmission handler circuit and a reception handler circuit transmits and receives data via the CAN core circuit by exchanging data with the volatile memory based on the configuration data stored to the configuration and status registers, and filter elements stored to the volatile memory. Specifically, the processing system further includes a hardware host circuit comprising a non-volatile memory configured to store first configuration data (CD1) and second configuration data (CD2). The CD1 includes configuration data to be transferred to the configuration and status registers of the CAN communication controller circuit and the CD2 includes at least one filter element to be transferred to the volatile memory. A control circuit manages an initialization mode, a reception mode and a transmission mode. During the initialization mode, the hardware host circuit stores the CD1 to the configuration and status registers and the CD2 to the volatile memory.
