摘要
The invention concerns the transmission of synchronous data between a master communication module and a slave communication module via a serial data bus, in particular a SPI bus. According to the invention, the data to be transmitted by each of the two master and slave communication modules are encapsulated in a data field (31) of at least one frame further comprising a frame identifier (30), and two frames are exchanged simultaneously between the two master and slave communication modules according to at least one predefined sequencing corresponding to a unique pairing of the identifiers of the two frames exchanged simultaneously. The integrity of a communication can therefore be controlled by verifying the sequencing of the exchanged frames.
