Abstract
In an embodiment a method for operating a processing system includes programming, by a microprocessor during a CAN FD Light data transmission phase, a control register of a Serial Peripheral Interface (SPI) communication interface of the processing system in order to activate a master mode; generating, by the microprocessor during the CAN FD Light data transmission phase, a transmission CAN FD Light frame; storing, by the microprocessor during the CAN FD Light data transmission phase, the transmission CAN FD Light frame to a memory; and activating, by the microprocessor during the CAN FD Light data transmission phase a first DMA channel so that the first DMA channel sequentially transfers the transmission CAN FD Light frame from the memory to a transmission shift register in the SPI communication interface.
