Abstract (en)
[origin: WO2007039634A2] The invention relates to a user interface (107) which is between a flexray-communication component (100), which is connected to a flexray-communication connection (101), via which messages are transmitted, and which comprises a message store (300) for intermediately storing messages from the flexray-communication connection (101) or for the flexray-communication connection (101), and a microcontroller (102) which is associated with the flexray-communication component (100) and which comprises a microprocessor (811) and a direct-memory-access (DMA) controller (812) for exchanging data with the message store (300). In order to improve the connection of the DMA-controller (812) of the microcontroller (102) to the flexray-communication component (100), the user interface (107) comprises a state machine (800) which automatically co-ordinates and controls data transfer between the message store (300) of the flexray communication component (100) and the DMA controller (812) according to the configuration by the microprocessor (811) of the microcontroller (102).
