Bugfix data synchronization after RTE start: In previous version invalid data may be transferred in case the communication is corrupted directly after RTE startup. Root cause was that the data was evaluated without caring if a communication error was reported. In the new version the startup condition and evaluation of data is only done if valid data has been received by the RTE => SPI communication is up and runnig.
