    Abstract: A processing system (10a) is described. The processing system comprises a Serial Peripheral Interface, SPI, communication interface (50), a microprocessor (1020), a memory controller (100) connected to a memory (104, 104b), and two DMA channels (DMA 1 , DMA 2 ) configured to transfer packets between the SPI interface (50) and the memory (104b). In particular, the processing system comprises an edge detector (600, 620) configured to assert a first control signal (IRQ 60 ) in response to a falling edge in the reception signal (RXD), a first hardware timer circuit (60) configure to, when enabled, generate a clock signal (PWM) for the SPI communication interface (50) and a second hardware timer circuit (62) configure to, when enabled, increase a count value and assert a second control signal (IRQ 62 ) in response to determining that the count value reaches a given threshold value.
    Specifically, the processing system (10a) is configured to manage a CAN FD Light data transmission mode and/or CAN FD Light data reception mode by using the SPI communication interface. For example, in the CAN FD Light data reception mode, the microprocessor (1020) activates a slave mode of the SPI communication interface (50), enables the first hardware timer circuit (60) and the second hardware timer circuit (62) in response to the first control signal (IRQ 60 ), whereby the second DMA channel (DMA 2 ) transfers packets from the SPI communication interface (50) to the memory (104b), thereby sequentially transferring a reception CAN FD Light frame from the SPI communication interface (50) to the memory (104b), and reads the reception CAN FD Light frame from the memory (104b) in response to the second control signal (IRQ 62 ).

    Abstract: A circuit (106) comprises a first (24a) and a second (24b) memory, a processing unit (21) and a timer (22). The processing unit generates a sequence of bits encoding a CAN frame and processes the sequence of bits to detect a sequence of PWM periods. Each PWM period has a dominant portion and a recessive portion, and a total duration. The processing unit stores values of a first parameter of the PWM periods into the first memory, and values of a second parameter of the PWM periods into the second memory, wherein the first and second parameter define a shape of the PWM periods. The timer comprises a first register (220) which reads from the first memory a value of the first parameter of a current PWM period. The timer comprises a counter (221) which increases a count number and resets the count number as a function of the value of the first register. A value of the first parameter of a subsequent PWM period is stored into the first register as a function of the value of the first register. The timer comprises a second register (222) which reads from the second memory a value of the second parameter of the current PWM period, and compares the count number of the counter circuit to such value. The second register drives an output pin (230) to a dominant (resp., recessive) value as a function of said comparing the count number of the counter circuit to the value of the second register. A value of the second parameter of a subsequent PWM period is stored into the second register in response to the count number reaching the value stored in the first or second register.
