Method for communicating between a microcontroller and a transceiver component

摘要

A method for communicating between a microcontroller and a transceiver component. The microcontroller includes a first pin for transmitting output data to the transceiver component. The microcontroller includes a second pin for receiving input data from the transceiver component, which includes a first input for receiving the output data. The transceiver component includes a first output for transmitting the input data. The transceiver component includes an interface for a data bus. The transceiver component transmits output data via the interface and receiving input data via the interface. The transceiver component includes an additional function device with a second input and a second output. Additional data are at least intermittently transferred from the first pin to the second input via the first input, and/or from the second output via the first output to the second pin. A device and a computer program via which this method may be carried out.
