    Abstract: A device includes a master device, a set of slave devices and a bus. The master device is configured to transmit first messages carrying a set of operation data message portions indicative of operations for implementation by slave devices of the set of slave devices, and second messages addressed to slave devices in the set of slave devices. The second messages convey identifiers identifying respective ones of the slave devices to which the second messages are addressed requesting respective reactions towards the master device within respective expected reaction intervals. The slave devices are configured to receive the first messages transmitted from the master device, read respective operation data message portions in the set of operation data message portions, implement respective operations as a function of the respective operation data message portions read, and receive the second messages transmitted from the master device.

    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: 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.
