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 embodiment processing system comprises a queued SPI circuit, which comprises a hardware SPI communication interface, an arbiter and a plurality of interface circuits. Each interface circuit comprises a transmission FIFO memory, a reception FIFO memory and an interface control circuit. The interface control circuit is configured to receive first data packets and store them to the transmission FIFO memory. The interface control circuit sequentially reads the first data packets from the transmission FIFO memory, extracts at least one transmission data word, and provides the extracted word to the arbiter. The interface control circuit receives from the arbiter a reception data word and stores second data packets comprising the received reception data word to the reception FIFO memory. The interface control circuit sequentially reads the second data packets from the reception FIFO memory and transmits them to the digital processing circuit.

Abstract: In accordance with an embodiment, a method includes determining whether a frame received from a communication bus is encoded according to a particular communication protocol and is addressed to a particular electronic device; increasing a frame count value when the frame is encoded according to the particular communication protocol and is addressed to the particular electronic device based on the determination, wherein increasing the frame count value comprises increasing a count of a modular arithmetic counter circuit having a first bit depth, and the frame count value is constrained to a modulus value of the modular arithmetic counter circuit; setting a frame count status bit based on comparing the frame count value to threshold values, and transmitting a frame comprising the frame counter status bit over the communication bus, and resetting the frame count value at an end of a monitoring time interval.

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: A processing system includes a digital processing unit programmable as a function of a firmware stored to a non-volatile memory and a resource connected to the digital processing unit via a communication system. The processing system also includes a time reference circuit including a first digital counter circuit to generate, in response to a clock signal, a system time signal including a plurality of bits indicative of a time tick-count, and a time base distribution circuit to generate a time base signal by selecting a subset of the bits of the system time signal, wherein the time base signal is provided to the resource. The resource detects a given event, stores the time base signal to a register in response to the event, and signals the event to the digital processing unit. The digital processing unit reads, via the communication system, the time base signal from the register.
